Sisal is a natural fiber derived from the Agave plant, a member of the cactus family. Sisal fiber is strong, durable, and 100% biodegradable. Place a full bar of soap or your soap scraps in this bag for a rich lather and gentle exfoliation. You can also use this as a soap holder instead. This will help your bars to last longer in the shower by hanging it and allowing it to dry in between uses. Bags measure 4x6.
