Crystal Glass, Genuine Czech 5 Inch Nail File in Red Hard Case

The overlap between the two sides of the cover should be greater, or the cover should close more securely. The two halves of the case came loose several times in my makeup bag. Unfortunately, because the file is glued into one half of the case, any slight lateral pressure on the cover when it is not fully secure will put a lot of force on the glass file itself. For me, this inevitably led to the file breaking off inside the cover.The way the cover is rounded/angled off at the overlap point looks nice, but it decreases the actual amount of overlap between the two halves. Since only friction holds the two halves together (no positive latch or "snap" together), less overlap = less friction = weaker connection. This is a good idea for a product, but it was not executed well.I tossed mine after it broke and replaced it with  Nail Tek Mini Crystal File with Pink Case  which has a greater overlap between the two halves of the cover. I've been happy with it except for how it lacks a pointed end to the file like the Mont Bleu one has. At least it's still intact, though!

This is a great nail file. I really like that it has a cover that slides over the file. I had a glass files in the past that had a case but it moved around in the case and broke. It does a much better job than a metal or disposable file.

These are the best, I had one for many years but sadly it broke and I have been looking for this file with case for years and finally found it.

A permanent file. Don't by the cheap ones. They have gasses crystals glued on and they wear out rapidly. These have etched glass. I had one for 5 years but lost it😟 Was glad to find these. Hard case keeps it safe.

My son, who plays classical guitar and must have properly-shaped nails, loves these glass files with the nice handle and handy cover. I've ordered several as previous ones get lost or broken, and he keeps requesting them.

I like it. Works well. The file area is a bit "short". A longer file would be an improvement.

Very good

These files are the best! I like this one because of the case. Highly recommend this
