Our natural, porous stones have gentle abrasive properties. Soak your feet in warm water until your skin softens, then gently rub the pumice stone over calluses to remove dead skin. Comes with a loop for easy hang drying in between uses.  A pumice stone aids in removing dead skin cells and can treat hard calluses, reducing friction and pain. Adding a pumice stone to your skin care routine can improve cracked heels by removing the layers of hard skin, cleaning, and prepping your heels for a moisturizing treatment. How to: * Soak your skin in warm water for at least 5 minutes to help soften it. * Add your pumice stone to the water.
