Perfect Formula Glass Nail File (Set of 2) - Crystal Nail Files with Case - High Quality, Professional Czech Glass Nail File

Fantastic nail files, I’ve been using them for years. Best nail file I’ve ever used! Especially important with stressed or fragile nails. I believe they’ve helped improve my nail condition, they are stronger because they’re not catching on things ecause the edges are so smooth. So much better than emery boards! I always take one to the nail salon - brand new - on first visit.

Product arrived on time and in perfect condition. Thank you.

I don't have a way to verify this, but in their ad they show a closeup of nails filed using a regular nail file and theirs. The nails filed with theirs was noticeably smoother and undamaged so I thought I would give it a try. Can't verify without having the close-up equipment, lens, whatever that they used to photograph it, but the file does seem to be doing a good job of smoothing the nail edge.

These are the BEST nail files I have ever used. So much so, my husband actually asked for a set! These never dull, always ready to perform where normal nail files fail. Highly recommended

GREAT quality. Better price. Perfect size for all my traveling. My sister loved it so much she stole it. The glass is strong and it works wonders on my nails.

These are the best mail files I’ve ever used. Just be careful you don’t drop one cause they do indeed break like glass.

Great product. Last forever , unless you sit on them. Lol

Perfect Formula was my introduction to crystal files and I still have the original one that I purchased directly from the brand years ago. Nothing compares to these original ones. I've purchased others in the past two years or so and some weren't quite what they claimed to be and others were pretty decent but not quite in the same league as the original Pefect Formula files. These two new files are different from the originals in my opinion but overwhelming better than the majority of so-called crystal files out there.
