Rubis glass nail file, straight, single-sided surface

Best nail filer I've used. I don't really use it for filing my nails. I use it for removing the dead skin and callous on my fingers.

It is a good tool to have. I try to keep this kind of file around. It's great for ingrown, thick toenails. They are hard to find in the retail stores. Was very glad to find this one with much searching. Recommended.
