This is the powered pumice stone that removes dry, rough, and calloused skin on the feet and captures it via built-in suction. Its rotating head spins at two speeds (2,800 and 3,300 rpm), quickly and effectively buffing away hard, jagged skin on the sole and heel to leave feet softer and smoother. It can be held comfortably in one hand, producing salon-quality results with less time, effort, and mess than a standard pumice stone or metal foot file. Includes one 60 grit coarse exfoliating head, one 80 grit fine exfoliating head, and one 100 grit precision exfoliating head. Charges via USB.
