This isn't the best quality of glass nail file that I've ever seen, I have to be honest, but it does a great job. The case, as other have mentioned, is somewhat of a cheap looking plastic, but it does the job at protecting the file and stopping it from snagging on anything if you need to take it in your purse or bag.

The glass nail file works great on nails, I found compared to my usual nail file that there was a lot less frayed edges and snagging when I used this. While glass nail files, in general, do take off less nail at a time, this is still well and truly capable of removing a large chunk of your nail if you get over-zealous, so go slow when shaping.

Protip: When shaping nails always file gently in one direction to prevent breakage. If there are any frayed parts or under nail left you can use the blue side of a 'buff block' to clean it up.
