GENUINE CRYSTAL NAIL FILES - SMALL
Are a top-class product in nail care technology, having a non-porous, double sided filing surface that is acid-etched into the file surface. The filing surface will never wear through. Cheaper files have bonded grit in which epoxy is used to bond grit to the filing surface. The grit can wear off. We use a floating glass process. This is the process used to make expensive crystal files. Lower quality sheet glass process is used to produce cheaper files causing them to be thicker.
