A glass nail file is a reusable manicure tool that is used to shape and the edges of natural nails. It’s made out of hardened glass with a fine, abrasive surface that gently helps to remove small parts of the nail.
This style of nail file is also sometimes known as a ‘crystal nail file’. They are smoother than emery boards and can last much longer if they are looked after well and stored carefully.
This means that a good-quality glass file lasts a lot longer than a disposable emery board and doesn’t become smooth as soon.
What is a Glass Nail File Made Of?
A glass file is usually made out of hardened or tempered glass. The surface that removes the your nail surface is etched onto the glass; it isn’t an extra abrasive layer that is stuck on like it is on an emery board.
Cheaper glass files may have a stuck on surface, similar to an emery board. This can wear out over time, so check whether a board has the abrasive surface permanently etched on before you buy it.
How Does a Glass Nail File Work?
Like an emery board, the textured surface wears away the free edge of the nail as it’s moved across.
Because the texture is smoother, a glass nail file can leave your nail smoother than an emery board would be able to achieve. It’s particularly good for making small adjustments, shaping, and smoothing rough edges.
When using a glass file, use light pressure instead of pressing hard.
What are the Benefits of a Glass Nail File?
A glass nail file can be:
- Reusable
- Easy to clean
- Gentle on natural nails
- Suitable for smoothing rough edges
- Longer lasting than disposable files
- More resistant to absorbing moisture and debris
Can You Use a Glass Nail File on Natural Nails?
Yes, glass files are very commonly used on natural finger and toenails.
They are best for shaping the nail, rather than quickly removing a large amount of length. If your nail is very long, it might be quicker to clip it with nail clippers, before then finishing off with a file.
Avoid filing a nail if it’s painful or infected.
How Should You Use a Glass Nail File?
Place the file alongside the free edge of the nail and use gentle, controlled strokes.
Many glass files can be used in any direction, as their surface is fine and uniform. However, you still need to avoid filing too aggressively, as this can make the surface rough and uncomfortable.
Make sure you don’t remove more nail than you meant to by stopping and checking the nail regularly.
How Do You Clean a Glass Nail File?
Rinse the surface under warm water and remove any stuck nail dust. You can use a bit of soap to make this process more efficient.
Before you then put the file away, make sure that it has fully dried.
Check the manufacturer’s instructions before using very hot water or disinfectants, as different files can react differently if cleaned too harshly.
Where Should You Store a Glass Nail File?
You can store your file in a protective cover, so that it’s not knocked. Many files come packaged in a case, which is suitable for long-term storage.
Glass nail files can chip and break if they are dropped. To help preserve yours and keep it clean, don’t store it loose at the bottom of a manicure bag.
How Long Does a Glass Nail File Last?
A high-quality, etched file last for years if you clean it and protect it from getting broken or chipped.
The surface should continue to work because the abrasive structure is part of the glass, rather than being stuck-on particles that rub off with use. A coated file, however, may rub away as it is used.
Replace your file if it gets chipped or cracked.
Glass Nail File vs Emery Board
A glass file is reusable and has a finer surface.
An emery board, on the other hand, is made by attaching abrasive material or a piece of cardboard or foam.
Emery boards are quite cheap and good for shaping the nail quickly, but they wear down and get clogged with nail dust. Glass nail files are a bit more of an upfront investment, but they can be cleaned more thoroughly and should last a lot longer.
Can You Use a Glass File on Artificial Nails?
Yes, you can still use a glass nail file on false nails.
However, as glass files are quite fine, they might be slow if you are trying to remove quite a bit of length or really change the shape of a press-on nail. You may be better off with a coarser file that is specially designed for use on artificial nails.
You can then use a glass file to make small touch ups on the edges, to for smoothing.
Is a Glass Nail File Worth Buying?
A glass file may be worth buying if you regularly shape your natural nails and want a reusable alternative to an emery board.
If you prefer a coarser file, in order to remove more nail, or you don’t file your nails very often, a glass file may not be worth it for you.
Final Thoughts
A glass nail file is a tool that uses textured, hardened glass to remove small amounts of the nail edge. It can shape and smooth natural nails in a controlled manner, and can last for a long time if looked after properly.
It’s more durable and easier to clean than an emery board, although it can still break if dropped or mishandled.
