"The abrasive qualities of this pumice stone make it a perfect solution to gently exfoliate and smooth heels, and to remove the rough and callused area of the feet, toes, hands, elbows, and knees. The unique shape of this stone makes it so handy and so easy to reach the various curves of your feet. Direction: Soap up your feet. Wet the stone with warm water and rub firmly over the dry or hard skin. Use it every day to help restore its natural softness. Do not use if you have diabetes or poor blood circulation problem. Rinse the stone thoroughly after each use and allow it to air dry."
