Traditional cardboard files are rough on nails and may shed layers of keratin and thin the nail, making it prone to chipping and breaking. To avoid this, nails are filed in one direction only. Crystal files seal the layers of keratin during the shaping process, eliminating the need to file in one direction. A crystal file can be used on natural and artificial nails. When shaping artificial nails, dip the crystal file in water before use and also periodically throughout the shaping process to keep filings from building up.
Between uses, wash your crystal file with soap and water and a scrub brush to remove nail debris. Beauty supply stores sell sterilizing sprays for use after washing.
Crystal files are prone to breakage. Always store your crystal file in its original case. Discontinue using a crystal file that is chipped or otherwise damaged. Children should only use crystal nail files under adult supervision.
