The Powered Pedicure Pumice Stone gently and effectively transforms hard callused feet into supple touchable feet. Spinning at 30 times a second, it is a safe alternative to harsh metal scrapers. Just choose one of the 2 specially designed pumice rollers (course or extra course) to buff away rough callused or hard jagged skin on your soles or heels. It’s like a hand-held pedicure! The unit is simple to clean, just use running water. Ergonomically designed to be easy to grip, yet small enough to slip into an overnight bag – there’s no excuse for you to have rough unsightly feet ever again.
