Review: Brilliant and easy to use! - Wow! I'd never heard of Czech glass nail files before. I was searching for an enamel one when this one popped up on my search. I then googled "Czech glass nail files," and read all about them and found several websites with dozens of glowing reports, with not one complaint! So I took the bull by the horns and came back to desertcart and ordered this one - tbh, it was hard to choose which colour, maybe I'll buy one of each eventually, one for each room! This glass nail file makes filing fingernails an absolute doddle - it just glides so smoothly, you only need one swipe, not several like a normal emery board or metal file. Then all you have to do is hold it under a running tap for a few seconds, leave it on the side to air dry, and voilà! It's good to go again, or store it back in its lovely hard case. My sister has very hard big toenails that normally the podiatrist has to tackle, but I sent her a glass file and she said it's brilliant and easy to do herself now. I definitely recommend you buy one. It won't disappoint. (And while I'm here, let me also recommend the Czech glass foot file. Also much easier and better than a pumice stone.)
Review: High quality - Wow. I mean wow. I wasn't sure about this file but it proved me wrong. It filed my natural nails effortlessly and did break them. I have thin nails and this was gentle yet effective, very fine grain, my nails were smooth in a couple of goes. I imagine someone with thicker nails will take a but longer, but I see this nail file will work for all types of nails, natural and synthetic.

## Features

- Bona Fide Beauty Glass Nail Care Tool: Expertly shape with genuine high grit Czech glass nail filers! This ombre blue fingernail file glides gently in any direction across the nail, with no irritating scraping sensation. Perfect nail tool even for those new to doing their own manicure at home!
- Strengthen, Smooth and Harden Fingernails At Home: achieve healthy fingernails with regular and long-term use of a genuine Czech glass nail file. Save time and money by achieving salon results from home!
- Trim, Smooth and Shape with Glass Nail Filers: forget traditional harmful nail files that tear, shred & damage the keratin layers of your nails. Bona Fide Beauty Czech glass fingernail files seal the keratin layers, leavings nails smooth with no jagged edges.
- Easy to Clean - To clean a glass nail filer, rinse it under cool running water to remove nail dust. Apply a small amount of mild soap and optionally use a soft toothbrush to gently scrub the surface. Rinse thoroughly, let it air dry, and once dried, it can be used again.
- It's Still Glass! Though made of tempered glass, the glass nail file can break if dropped or tapped against hard surfaces. With proper care, a Czech glass file can last a long time, making it a reusable and sustainable choice.
