Use the Pumice Pad on hands, heels, elbows, knees and feet to smooth rough and callused skin. For best results use the Pumice Pad after skin has been soaked and softened in the tub, shower or basin. Soak the Pumice Pad with water, then rub over calluses, corns or hard skin for a soft smooth finish. It may also be used to remove ink, nicotine stains, dirt, tree sap, and more hard to remove stains.
