Pumice stones are a natural beauty tool made by mixing lava with water and forming it into a light, yet abrasive, stone. While your skin is moist, either in or right after a shower or bath, rub the stone on your feet, knees, and elbows to remove calluses and rough spots leaving smoother skin. When finished, apply an oil or moisturiser.

Loop for hanging.

After use, run under warm water and hang dry. 

Lava stones are handmade and will vary and shape, weight, and size. And, might also have imperfections. All lead to their charm.
