Torn and split nails may be prevented by regularly filing your nails into shape. Crystal Nail File files your nails gradually and smoothly into shape, perfectly locking the nail thanks to its fine structure. The fine yet strong structure of the glass makes the file suitable for any nail type, very hygienic to use and lasts at least 10 times longer than ordinary files.
The result: beautiful nails without disfiguring irregularities.
