What grit is the file?
When it comes to Czech glass nail files, determining grit in the classic sense is not as simple as it is with metal nail files. To explain, the different grit levels in typical Metal Nail Files are similar to those of sandpaper, i.e. the higher the number the smoother the file (or the number of pieces of grit per square inch).

In regards to Czech Glass Files, because the grit is formed out of the body of the file itself, and not manufactured then attached to the file separately like it is with metal files and emery boards, determining grit in a classic sense is a little more difficult.

Bona Fide Beauty offer two types of grit, both of which fall within a 240 grit range.

BFB’s Standard Grit which is fine somewhat medium. It has a higher grit then most emery boards, but a lower grit then metal files, which are generally quite coarse and harsh on natural nails.

Our standard (fine~medium) grit suits most nail types and is particularly good for people with ‘normal’ or reasonably healthy nails. The abrasive surface of these files feels similar to the roughness of a cat’s tongue, an odd example but surprisingly accurate.

We also offer files with a distinctly fine grit, which is most likely a 240 - 400 grit range. This grit is ideal for people with more fine, sensitive or fragile nails. The abrasive surface of this file feels like smooth glass, however, it still files the nails perfectly.

Some people have strong, thick nails while others may have fine, sensitive nails. While Bona Fide Beauty Czech glass nail files suit most nail types, everyone’s nails are different. We suggest trying a 1-Piece file to start and see if it is the right fit for you and your nails.

Czech Glass Files are designed to be a gentle nail care tool. We recommend using your BFB Czech glass file regularly to file and shape the nail. Bona Fide Beauty Czech Glass Nail Files seal the keratin layers together leaving the nails smooth and healthy. They can also be used to file in both directions without damaging the nail which is a big bonus. Regular, long-term use can contribute to healthier, stronger nails.

Do the files come with a protective sleeve?
Bona Fide Beauty Files either come with a protective plastic sleeve or plastic hard case, please check the Amazon listing carefully prior to making your purchase.

How long will the filing surface last?
Czech Glass Nail Files are very durable long lasting. If treated with care they can last you a number of years. The files are made from chemically hardened Czech Float Glass of the finest quality. The surface of the file is chemically etched so it won’t wear off like an emery board or other cheaper nail file alternatives.

In our experience, some customers choose to replace their files after 12 - 24 months, while others can have a glass files for 5+ years!

A unique feature of Czech Glass Files is their ability to be used over and over again due to their durability and hygienic nature.

What makes Czech Glass Nail Files Hygienic is their non-porous glass surface, which does not absorb water and in turn prevents the growth of nasty bugs and fungus to grow. You can wash them under water, dry them off and use them again, unlike other files which should be thrown away after a few uses due to the risk of unhealthy hygiene.

As you continue to use your Glass File, the surface will feel smoother over time, but will still file the nail efficiently. BFB's Czech Glass Files are designed for regular, long-term use. We recommend using them on a regular basis to file, shape and strengthen the nail. They feature a fine to medium grit which is gentle on the natural nail. They help seal the Keratin layers of the nail together leaving the nail smooth and contributing to nail health with regular use.

Unlike emery boards, metal files or paper files which often need to be thrown away after only a short while, the glass file will continue to work perfectly after many uses, making it a more environmentally friendly nail care tool.

Is it normal if my file squeaks as I file?
If your file makes a slight squeaking sound as you file, this is normal. It is caused by the friction between the glass and your nail.

When I file I can smell a odour, is this normal?
On rare occasions, some people experience a slight smell after filing, this too is very natural.

As you file your nail, you are exposing bacteria that resides in the nail, thus causing the smell. We recommend keeping your nails as clean as possible between filing. You can also use organic air freshners or essential oils to mask the smell.
