What Are Emery Boards and How Do They Help Your Nails?

 

Keeping your nails neat and well-shaped is a small but meaningful part of everyday personal hygiene. Emery boards have been a staple of nail care routines for decades — and for good reason. The Numark Emery Boards 17cm offer a simple, affordable way to shape, smooth, and maintain both fingernails and toenails at home, without the need for salon visits or specialist tools. At just £1.79, they're one of the most accessible nail care products you'll find. If you're also looking after your overall skin health, you might find our skin care collection a useful companion to your grooming routine.

These boards measure 17cm in length, making them easy to grip and manoeuvre — particularly useful when filing toenails, which can be harder to reach. Each board is double-sided, with a coarser abrasive surface on one side and a finer grit on the other, giving you two levels of filing in a single tool.

 

How Do Numark Emery Boards Work on Your Nails?

 

The mechanism is straightforward. The abrasive coating on each side of the board — made from crushed emery mineral bonded to a card or foam core — physically removes tiny layers of the nail's free edge when drawn across it. Think of it like very fine sandpaper for your nails. The two-sided design means you can:

  • Use the coarser side to reduce nail length and shape the overall outline
  • Use the finer side to refine the edge, remove snags, and leave a smooth finish
  • Work on both fingernails and toenails with the same board
  • File gently without the harshness of metal files, which can cause micro-fractures in the nail plate

Filing in one direction — rather than a back-and-forth sawing motion — is the key to avoiding nail splitting. This is a point worth remembering, especially if your nails are naturally thin or prone to peeling.

 

Who Should Use Numark Emery Boards 17cm?

 

These emery boards are suitable for most adults and older children who want a quick, fuss-free way to maintain their nails. They're particularly well-suited to:

  • Anyone who prefers a gentle filing option over metal or glass files
  • People who want an affordable, disposable nail care tool
  • Those who need a longer board for easier grip when filing toenails
  • Individuals who travel frequently and want a lightweight, compact nail file

That said, people with certain health conditions — such as diabetes, peripheral neuropathy, or circulatory problems — should take extra care when filing nails. Reduced sensation in the fingers or toes can make it harder to judge pressure, increasing the risk of accidental skin abrasion. If you're unsure, speak to your GP or a podiatrist before using any nail file.

 

How Do Numark Emery Boards Compare to Other Nail Files?

 

Feature Numark Emery Boards 17cm Glass Nail File Metal Nail File
Grit options Double-sided (coarse & fine) Single fine grit Single or double-sided
Gentleness on nails Moderate — suitable for most Very gentle Can be harsh
Hygiene / reusability Disposable — single use recommended Washable and reusable Washable and reusable
Price £1.79 (pack) £3–£10+ £2–£8

 

Are Numark Emery Boards Suitable for Sensitive or Damaged Nails?

 

If your nails are brittle, thin, or recovering from damage — perhaps from gel polish removal or a fungal nail infection — you'll want to use the finer side of the board with very light pressure. Avoid filing nails that are wet or recently soaked, as this temporarily softens the nail plate and makes it more vulnerable to splitting. For those managing nail issues alongside a fungal infection, it's worth exploring our athletes foot and fungal infections collection for appropriate treatment options.

Store your emery boards in a dry place and replace them regularly. A worn board loses its abrasive efficiency and may drag rather than file cleanly — which can cause more harm than good. The Numark Emery Boards 17cm are designed as a hygienic, single-use or short-term tool, so replacing them frequently is both practical and advisable.

This product is a cosmetic grooming tool, not a medicine. However, if you have an underlying nail or skin condition, speak to your doctor or pharmacist before use.

Specifications of Numark Emery Boards 17cm

 

What Are Numark Emery Boards 17cm and What Are They Used For?

 

Numark Emery Boards 17cm are double-sided nail files used for shaping, smoothing, and maintaining the free edge of fingernails and toenails. They are a cosmetic grooming tool — not a medicine — and are available without a prescription. The boards are 17cm long, making them comfortable to hold and easy to use on both hands and feet. They are suitable for home use as part of a regular nail care routine.

Good nail hygiene is an important part of general health. The NHS notes that keeping nails clean and trimmed helps prevent the build-up of dirt and bacteria beneath the nail plate, which can contribute to infections. Emery boards are a gentle alternative to clippers for finishing and refining nail edges after trimming.

 

What Do You Need to Know Before Using Numark Emery Boards?

 

Although emery boards are a simple grooming tool, there are some important points to be aware of before use.

Do not use if:

  • The skin around your nails is broken, inflamed, or infected
  • You have an active fungal nail infection that has not been assessed by a healthcare professional
  • You have a condition that affects sensation in your fingers or toes (e.g. peripheral neuropathy)
  • You have been advised by a podiatrist or GP to avoid self-filing

Warnings and precautions:

  • Do not share emery boards between individuals — this can spread bacteria or fungal spores
  • People with diabetes should seek podiatry advice before self-filing toenails, as foot injuries can have serious consequences
  • Avoid filing nails that are wet or recently soaked, as softened nails are more prone to splitting
  • Keep out of reach of young children

Known interactions:

  • No drug interactions — this is a non-medicated grooming tool

 

How Should You Use Numark Emery Boards Correctly?

 

Using an emery board correctly makes a real difference to the health and appearance of your nails. Filing technique matters more than most people realise. Follow these steps for the best results:

  1. Start with clean, dry nails — avoid filing immediately after bathing or washing hands
  2. Hold the emery board at a slight angle beneath the nail's free edge
  3. Use the coarser side to shape the nail, filing in one direction only (not back and forth)
  4. Work from the outer edge towards the centre on each side
  5. Switch to the finer side to smooth any rough edges or snags
  6. Brush away any nail dust with a soft nail brush
  7. Dispose of the board if the abrasive surface becomes worn or contaminated
Indication Age Group Recommended Use Frequency
Fingernail shaping Adults & older children Coarse then fine side As needed
Toenail smoothing Adults Fine side only for finishing As needed
Brittle or thin nails Adults Fine side only, light pressure Infrequently

If you're also managing foot health more broadly, our foot care collection includes a range of products to support healthy feet alongside your nail care routine.

 

What Are the Possible Side Effects of Using Numark Emery Boards?

 

Emery boards are generally very well tolerated. However, incorrect use can occasionally cause minor issues.

Common issues with incorrect use:

  • Nail splitting or peeling — usually caused by filing in a back-and-forth motion
  • Nail thinning — from excessive pressure or over-filing
  • Minor skin irritation if the board accidentally contacts the surrounding skin

Less common concerns:

  • Nail plate damage in people with pre-existing brittle nail conditions
  • Worsening of an existing nail infection if filing is performed over infected tissue
  • Inhalation of nail dust — file in a well-ventilated area if you are sensitive to dust

If you notice signs of a nail infection — such as discolouration, thickening, or pain around the nail — stop filing and seek advice from your pharmacist or GP. The NHS provides guidance on nail conditions including fungal nail infections, which are more common than many people realise.

 

How Should You Store Numark Emery Boards?

 

Proper storage keeps your emery boards in good condition and maintains hygiene between uses.

  • Store in a cool, dry place away from moisture and humidity
  • Keep away from direct sunlight, which can degrade the adhesive bonding the abrasive coating
  • Do not store in a damp bathroom cabinet if possible — a bedroom drawer is preferable
  • Keep out of reach of children
  • Replace boards regularly — a worn board is less effective and may cause nail damage

For a broader range of personal care and hygiene products, you might also find our oral health collection useful as part of your daily health routine.

How do emery boards work on nails?

Emery boards work by using a mineral abrasive coating to physically file away the free edge of the nail when drawn across it. The coarser side removes length and shapes the nail outline, while the finer side smooths and refines the edge. This two-sided design means you get a complete nail-shaping result from a single tool.

How do I use Numark Emery Boards step by step?

Start with clean, dry nails — never file wet nails as they are more prone to splitting. Hold the board at a slight angle beneath the nail's free edge and use the coarser side to shape, filing in one direction only. Finish with the finer side to smooth any rough edges, then brush away nail dust with a soft brush.

What is the correct technique for filing nails with an emery board?

The most important rule is to file in one direction only — from the outer edge towards the centre — rather than using a back-and-forth sawing motion. Sawing weakens the nail structure and can cause splitting and peeling over time. Use light, even pressure and let the abrasive surface do the work rather than pressing hard.

Can I use emery boards on toenails as well as fingernails?

Yes, Numark Emery Boards 17cm are suitable for use on both fingernails and toenails. Their 17cm length makes them particularly practical for reaching toenails comfortably. Use the finer side for toenail finishing, as toenails tend to be thicker and less prone to splitting than fingernails.

Are emery boards safe for people with diabetes?

People with diabetes need to take extra care with all foot and nail care, including filing. Reduced circulation and nerve sensitivity in the feet can make it difficult to judge pressure, increasing the risk of accidental skin injury. The NHS recommends that people with diabetes seek advice from a podiatrist for foot and nail care — check our foot care collection for supportive products.

How often should I replace my emery board?

Emery boards should ideally be replaced after each use, or at minimum when the abrasive surface becomes visibly worn, smooth, or clogged with nail dust. A worn board drags rather than files cleanly, which can cause nail damage. For hygiene reasons, never share an emery board between different people.

What are the alternatives to emery boards for nail care?

Common alternatives include glass nail files, metal nail files, and electric nail buffers. Glass files are very gentle and washable, making them a good long-term investment, while metal files are durable but can be harsh on thin or brittle nails. Emery boards remain one of the most affordable and widely available options for everyday nail maintenance.

Can emery boards cause nail damage if used incorrectly?

Yes — incorrect technique is the most common cause of nail damage from filing. Filing in a back-and-forth motion, applying too much pressure, or filing wet nails can all lead to splitting, peeling, and thinning of the nail plate. Always use light, unidirectional strokes and avoid over-filing the same area repeatedly.

Who is eligible to use Numark Emery Boards 17cm?

These emery boards are suitable for most adults and older children as a general grooming tool. They are not recommended for use on broken, infected, or inflamed skin around the nails. People with diabetes, peripheral neuropathy, or other conditions affecting nail or skin health should consult a healthcare professional before self-filing.

What happens if I accidentally file the skin around my nail?

Minor skin abrasion from an emery board is usually superficial and will heal on its own. Clean the area gently with water and, if needed, apply a mild antiseptic. If the skin becomes red, swollen, or shows signs of infection, seek advice from your pharmacist or GP promptly.

How long can I keep using the same emery board?

Emery boards are designed as short-term, disposable tools rather than long-lasting reusable files. Once the abrasive surface becomes smooth or worn — which can happen after just a few uses — the board should be replaced. Continuing to use a worn board is less effective and may cause more friction and nail damage than a fresh one.

Are Numark Emery Boards suitable for brittle or weak nails?

Yes, but with care. If your nails are brittle or thin, use only the finer side of the board with very light pressure, and file infrequently. Avoid filing immediately after washing your hands or bathing. You may also want to consider a nail-strengthening treatment alongside your filing routine — our skin care collection includes products that support nail and skin health.

What is the difference between the two sides of an emery board?

The two sides of an emery board have different grit levels. The coarser side has a rougher abrasive surface designed to remove nail length and shape the overall outline of the nail. The finer side has a smoother grit that refines the nail edge, removes snags, and leaves a polished, smooth finish.

What are the latest recommendations on nail hygiene and care?

The NHS recommends keeping nails clean, trimmed, and dry as part of good personal hygiene. Filing nails regularly with a suitable tool — such as emery boards — helps prevent sharp edges that can snag or cause injury. Avoiding biting nails and keeping the skin around the nail moisturised are also recommended for maintaining healthy nails.

How Should You Use Numark Emery Boards 17cm?

Using your emery board correctly is the single most important factor in achieving smooth, healthy-looking nails without causing damage. Always start with clean, completely dry nails — filing wet or recently soaked nails significantly increases the risk of splitting and peeling. Follow these steps for best results:

Dispose of the board once the abrasive surface becomes worn or after use on an infected nail. Never share your emery board with another person.

What Is the Correct Dose of Numark Emery Boards 17cm?

As a grooming tool rather than a medicine, there is no "dose" as such — but the amount of filing you do matters. Over-filing weakens the nail plate, so use the minimum number of strokes needed to achieve your desired shape. The table below gives a practical guide to appropriate use by nail type and purpose.

When Is the Best Time to Use Numark Emery Boards 17cm?

The best time to file your nails is when they are completely dry — ideally before bathing rather than after. Nails absorb water and soften temporarily when wet, making them far more susceptible to splitting during filing. Many people find that filing nails in the evening, as part of a relaxed grooming routine, works well. Avoid filing immediately after using hand sanitiser or nail polish remover, as these can temporarily dry and weaken the nail surface.

If you are filing toenails, do so after they have been trimmed straight across with nail clippers, using the emery board only to smooth the edges and remove any sharp corners that could cause ingrown toenails.

How Long Can You Use Numark Emery Boards 17cm For?

Each individual emery board is designed for short-term use. Once the abrasive surface becomes smooth, clogged with nail dust, or visibly worn, it should be replaced — continuing to use a worn board is ineffective and may cause dragging that damages the nail. For most people, a single board will last between one and a few uses depending on how many nails are filed and how much pressure is applied.

There is no limit to how long you can incorporate emery boards into your nail care routine — they are a safe, everyday grooming tool for ongoing use. Simply replace each board regularly to maintain effectiveness and hygiene.

Do not exceed the recommended use. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Using Numark Emery Boards?

Numark Emery Boards 17cm are a non-medicated grooming tool and are generally very well tolerated when used correctly. The most common issues arise from incorrect filing technique rather than the product itself. If you experience any of the following, review your technique before continuing:

  • Nail splitting or peeling — most often caused by filing in a back-and-forth motion
  • Nail thinning — from applying excessive pressure or filing too frequently
  • Rough or jagged nail edges — usually the result of using a worn board
  • Minor skin irritation — if the board accidentally contacts the skin around the nail

What Are the Less Common Side Effects of Using Numark Emery Boards?

Less commonly, some people may experience the following, particularly if they have pre-existing nail or skin conditions:

  • Worsening of nail fragility in people with brittle nail syndrome or nutritional deficiencies
  • Aggravation of an existing nail infection if filing is performed over infected nail tissue
  • Sensitivity or discomfort in people with peripheral neuropathy who may not accurately gauge pressure
  • Mild irritation from nail dust in people with dust sensitivities — file in a well-ventilated area if this applies to you

What Are the Serious Side Effects of Using Numark Emery Boards?

Serious adverse effects from using an emery board are rare and almost always preventable. However, you should be aware of the following situations that warrant prompt attention. Filing over broken or infected skin can introduce bacteria and worsen an existing infection. In people with diabetes or poor circulation, even a minor skin abrasion near the nail can become a more significant wound if not managed promptly. If you notice increasing redness, swelling, warmth, or discharge around the nail following use, seek medical advice without delay.

What Should You Do If You Experience Side Effects?

If you accidentally abrade the skin around your nail, clean the area gently with clean water and apply a mild antiseptic if available. For minor nail splitting, avoid filing that nail further until it has grown out sufficiently. If you develop signs of a nail or skin infection — such as pain, swelling, discolouration, or pus — stop using the emery board on the affected area and consult your pharmacist or GP. Do not attempt to file over an infected nail.

For people with diabetes, any foot or nail injury — however minor it appears — should be assessed by a healthcare professional promptly, in line with NHS guidance on diabetic foot care.

Can Numark Emery Boards Interact With Other Products or Medicines?

As a non-medicated grooming tool, Numark Emery Boards 17cm have no known interactions with medicines or other topical products. However, if you are using a medicated nail lacquer — such as a treatment for fungal nail infection — avoid filing the nail immediately before or after applying the treatment unless specifically directed to do so by the product instructions or your pharmacist. Filing can alter the nail surface and potentially affect how topical nail treatments adhere and penetrate.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
