It’s made my nail care routine faster, easier and infinitely more pleasant.

While a traditional sandpaper-like file can leave nails feeling jagged, rough and full of micro-tears, my glass file slices through them cleanly, easily and smoothly, leaving them feeling healthy and strong. It takes a minute to get a hang of the rhythm of it, but once you do, it is a total game-changer. It can be used in all directions, which makes it easier to achieve the desired shape in less time. You don’t need a ton of pressure to make noticeable progress, either — I’ve been able to saw down relatively long nails swiftly and easily.

I love that my nails feel sealed, sleek and smooth, the way they do after a professional manicure. Jagged, dusty tips creep me out, but there’s none of that with these glass files. The file is tempered to make it strong and long-lasting, but I would imagine that if you dropped one from a great height it would likely break, so you do want to be careful. Luckily, each one comes with its very own protective case, which makes it ideal for slipping in a purse or travel bag.

The glass nail files from Bona Fide Beauty are available in nine colors. I find the clear one to feel very sophisticated (and I was feeling cheap the day I purchased it), but the colorful ones are super cute and only a couple dollars more expensive. If they feel like they’ve accumulated a bit of nail dust buildup, you can quickly clean them by giving them a rinse with plain water.

“Saw on Tik Tok and it’s a game changer for me. I like the smooth filing of the nail. I have not had any issues with this product so far.” —JS

“I wish I had discovered these years ago. Who knows how many nail files I have been through in my life but these, made of glass that doesn’t wear down quickly like traditional sandpaper-like nail files do, will last virtually forever. All you have to do is give them a quick rinse or wipe them with a terrycloth rag to clean them. I did step on one and broke it in half once so you have to be careful with them (after all, they are made of glass) but otherwise they are a Godsend. Highly recommended.” —InDaKnow

“This glass nail file works better than any nail file I have ever had. I will be reordering so that I have one in my purse, my car, and my makeup kit. Very good buy!” —M. Shalley Damberg

“This glass file is really fun! I had heard that glass files for the nails were really good. I ordered one and I simply love it. It is really soft on the nails and shapes them well and easy. The fingernails are so smooth after using this. Has its own little case for protection.” —Glenda F.

“A high quality product that works very well! Ever since I got this file, I haven’t used any of the old emery boards that I was used to using before.” —Maggie N.
