Product Overview
The grinding surface of ordinary paper or metal nail files is formed of grinding grains attached to a base. The grains tend to fall off after some time; the file gets blunt and needs to be replaced. The grinding surface of crystal glass nail files is created right out of the file body, by chemical action onto the glass surface. This way a practically unlimited lifespan of crystal glass nail files is achieved.
