This terra cotta pumice stone is perfect for dry, cracked heels and calluses. The two-sided foot scrubber works to cleanse, exfoliate and smooth skin. Used regularly, it helps remove calluses, and reduces dry, cracked heels. The "pumice" texture works to gently scrub away dry skin, and the "washboard" side helps polish skin. Terra-cotta, used widely in the Indian Sub-continent, is fired in a kiln, so it never wears out.
