It's time to upgrade from a traditional emery board.
By 
If you've been using the free nail file you got at your last manicure, it's time for an upgrade. A glass nail file, a.k.a. a crystal nail file, is easy to find and so much better for your nails. Not only are they more gentle, but can be used on natural nails, gels, and acrylics alike. Plus, they last longer—which translates to less waste. Ahead, we round up eight of the best glass nail files to add to your DIY manicure collection, and tap Tina Wang, owner of Lunula Salon in Brooklyn, New York, for her insight on the tool.

Frequently Asked Questions
What is a glass nail file used for?
They’re used to, well, file your nails. But they have added benefits regular emery boards don’t have. “Glass (or crystal) nail files serve the same function as emery boards, but glass files have a much finer grit that is easier on nail keratin,” explains Wang, adding that “Glass files are gentle, but very effective.”
Is a glass nail file better than a traditional nail file?
In general, yes, and Wang recommends them to clients that can’t come into her salon. “They are more gentle, low maintenance (just rinse with soapy water), and they last pretty much forever,” she says. Plus, they can be used on all nail types. “You can use them on natural nails, gels and even artificial nails,” says Wang.
How long do glass nail files last?
“Some manufacturers recommend every six months. However, it really depends on your nails and the usage, so replace your glass nail file when it loses its grit and is no longer able to shape nails easily,” recommends Wang. And although they are tempered, remember they are still made of glass. “Just make sure you don't drop them too often, because although durable, they can still crack."
