Beter Fibreglass Nail File

Suitable for hand and toenails, file on the medium-grained side (180) and outline on the fine-grained side (220).

A high grit number (280-220) means that it is composed of many grains but very small, so filing is smoother. And a low grit number (120-180), indicates that the grain is coarser, recommended for shortening or initial filing.
