Made from natural sisal. HOW TO USE: Place soap (scraps or a full bar) into the soap sack and close the drawstring. Rub the soap sack on the body for cleansing as you would a loofa. The soap sack helps build lather and allows you to use every bit of a bar! The soap sack can be hung to dry between uses to help make your soap last longer. TO CLEAN: put in the washing machine with a load of clothes.
