They are the greatest solution to quickly eliminate chipping, peeling, and splitting nails. They help your nails to become stronger and healthier leaving them with a very smooth finish. Nails are made up of Keratin layers that have a tendency to split and peel.
The glass crystal nail file will file the nail so smooth that it seals the edge of the nail eliminating the peeling, chipping and splitting. Genuine Crystal Nail Files are extremely hygienic since they are not porous and therefore do not create an environment for possibly spreading nail infections when used by more than one person.
Genuine Crystal Nail Files may break if mishandled, (they are made of glass after all), but will last forever if used properly.
