Mont Bleu Professional Set of 3 Czech Glass Nail Files - Genuine Czech Tempered Glass - Handmade Gift Set - Washable Double Sided Nail File - Etched Nail Files - Crystal Nail File for Natural Nails

These are great, while they do a good job filing they are also smooth enough to not mar the nail.

I've ordered numerous brands and this is my favorite glass nail file. Works great. Washes easily. You can file back and forth and not damage your nails.

I have searched for the past 4 -5 years for a nail file like this one. I had used a nail file that Opi sold and then quit selling. Hence my search. I did not know I should have been looking for Czech glass nail files. So on a guess, I decided to give this Mont Bleu Professional Set a chance. And Bingo! It is Just like the Opi one I've searched for. It gives that smooth yet effective movement on your nail with out beating it up. So glad I found this Czech glass one.

Good, if used properly.

I like how well they work no ripping or tearing of my nail. I wish they were longer

They are good. They work and don't destroy your nails.

All my life I've had thin, soft finger nails. This coupled with my propensity to still try to use than as tools has always left me with the problem my nails catching, tearing, getting nicked, etc., to the point that I've always had nail files on numerous locations, except my pocket, which would be the only solution with the various nail files I've been using.I thought I would try these. I got them towards the end of May. It's now mid-June. I have not had a single catch, tear, rip, since the time I used them.They seem to burnish the nails as well as file them. The files I was using never really left the edges smooth which is probably why they would always quickly get caught and tear on something.As a wood worker I am well familiar with burnishing things to an ultra smooth finish where there is no hint of roughness. That's exactly what these nails files do.I love in the country where there's no shortage of big bites. The first thing I noticed after using these nail files was that it became more difficult to scratch itchy bug bites. They were too smooth. A small price to pay. And probably much better for my skin as well. With the old nail files I was using it was very easy to get significant skin damage with just a little scratching, usually done half asleep. Haha.Anyway great product. I can imagine these lasting a lifetime of you A) don't use them to try file metal, B) don't use them as pry bars, C) don't use them as screwdrivers, and D) don't throw them around.They seem quite sturdy using them as they are intended. Finger nails begin softer than glass cannot possibly wear them out. This is simple physics.

These files leave smooth edges. They are very nice to use.
