Using the Pumi Bar couldn’t be simpler. Depending on your preferences, you can either use it dry, or you can wet the callused area of your skin with soap and warm water before use. Rub the bar around your toes and the soles of your feet to remove the calluses and tough epidermis. You can also use the bar on elbows and hands. Afterward, rinse the pumice bar under hot water to clean it.
