This is the powered pedicure aid that quickly and gently removes dry, rough, and calloused skin on the feet. The device's unique micro-mineral roller spins at 1800 rpm, quickly and effectively buffing away hard, jagged skin on the sole and heel to leave feet softer and smoother. Similar in size to an electric razor, the lightweight roller can be held comfortably in one hand, producing salon-quality results with less time and effort than a pumice stone or metal foot file. Comes with two coarse rollers; each roller lasts up to six weeks when used three times per week. Requires two AA batteries. 7" L x 4" W x 2" D. (6 oz.)
