This is the easy-to-use, battery-operated PURSONIC Nail Clipper. Its 1/2"-long x 1/16"-wide alloy bit spins at 500-rpm, enabling its precisely beveled blades to safely and gently trim nails as you nudge your fingernail against the bit - all without the need to squeeze the fingers, bend the wrist, or risk cutting the cuticle. Fitting comfortably into the hand with an ergonomic grip, the trimmer's easy push-button control allows for brief trims with each press or constant trimming when the button is pushed forward into its locked position. Requires two AA batteries. Head removes for easy cleaning with the included brush. Used For: Trimming. For Use On: Nails. Includes: Nail Clipper. Power Source: Battery-Powered.
