Pumice stones are used to keep your feet smooth.  Great for daily use after you've received a pedicure.  If you notice that you have more severe unwanted skin, it's recommend you exfoliate with a Battle Baddle.
 
How to Use: With a wet pumice stone and wet feet, scrub in multiple directions over heels or dry areas of feet. Important to rinse dead skin layer of stone and repeat scrubbing in all different directions.
Maintenance: After use, wash with antibacterial soap & hang to dry. Replace stone every month.
 
Important: If the stone is chipped or cracked DO NOT use.
