Dr. Dana Precision Glass Nail File

Regular use of our Precision Glass Nail File strengthens and seals the nail’s keratin layer, to make nails more resistant to splitting, peeling, and breakage.

Designed for natural nails: Many nail files, including crystal, glass and traditional emery boards, are too abrasive for natural nails and can cause microscopic tears at the tip of the nail that lead to breakage, damage, and premature polish chipping. Natural nails—especially if they are delicate, damaged or fragile—require a completely different technology.

Directions: File dry, natural nails to desired length. After use, clean with water and allow to air dry.
