Glass Nail File and Nail Shiner, 4PC Crystal Nail File and Nano Glass Nail Buffer, Premium Set with Case, Professional Manicure Tool Fingernail Czech File for Natural Nail, Gift for Women and Girls

Love this - I've used it many times and it hasn't dulled, it still files my nails the same as when I bought it. Replaces many disposable products. I had a stain on a fingernail and this removed it when everything else wouldn't. It really does shine your nails beautifully which is really helpful when I want to be very presentable with natural nails without polish

Haven’t used it much yet , but do like the set and think it will be great!!!

Beautiful set with a bonus set of smaller size as well!

I did some research before going out and buying a nail file. I was sick and tired of the sprayed on/pad garbage most nail files are. I found out that there are glass nail files and crystal nail files that have a chemically engraned pattern that will be much better than sprayed on coatings.Pros:I haven't taken a coin to scrape this nail file kit but from the feel and the way it works, the glass files are legit. As far as the crystal (dull) looking ones, I believe they are real and not coatings as well.My nails do in fact get shiny. The smallest glass nail file, I believe, is the shiner... works very, very well. Takes off a bit of nail if you use it too much but cleaning it is great. The glass "micro-grooves" or whatever don't come off and are really engrained.Cons:I wish it wasn't as thick. I haven't dealt with many nail files before but I just wish it was a millimeter thinner for easer access on the sides of the nail.I also wish there were some instructions as to what file is for what... there is a longer glass file that has two patterns on it and a shorter one with one pattern on it. I wish I knew the "grit" (its not actually grit but I'm not sure what else to call it) on each of those files to know which one would be the best for shining. Like I said before, the smallest one seems to work the best so I think that one is the finest.Conclusion:I really enjoy this product. It works wonderfully, believe it or not, and I think this 10$ (at the time of this review) will be a lifelong investment; I don't see this product wearing out any time soon. Very pleased.

These files take some getting used to because they work fast. The file cuts right into even the toughest nail. The nail file holder also contains a file that files down the surface of your nail softly enough that your nail look like they have been buffed to a shine, even without polish. The case comes with exactly as is advertised.

I didn't know glass nail files were a thing until I came looking for an emery board with a case to carry in my purse. The reviews seemed pretty good, and I figured this set was inexpensive enough to take a risk on this fancy new nail technology. Worth it. The buffer was a huge bonus. Both work really well

Great product! Easy to use. Easy to clean.
