Frequently Asked Questions

Why choose a glass nail file instead of an emery board?

Glass nail files create a smoother finish, are reusable, and are generally gentler on natural nails than traditional disposable files.

Can I wash the file?

Yes. Simply rinse with water and mild soap, then dry thoroughly before storing.

Can I use it before applying press-on nails?

Absolutely. A smooth nail edge helps create a cleaner, more polished manicure and prepares your nails before application.

Will the filing surface wear out?

With proper care, the tempered glass surface is designed to maintain its performance much longer than standard nail files.
