This exfoliating soap bag is made of sisal material and cotton rope. It is reusable and lightweight and helps create an excellent lather for soap. 
 
Sisal is a natural fiber derived from the long, green leaves of the 'agave sisalana' cactus plant.  Sisal is softer than loofah yet still provides enough scrub to leave skin refreshed.  
This all natural sisal soap saver is terrific for exfoliating skin.  It also allows you to use up every sliver of your soap bar, saving you from wasting any soap!
 
Easy to use: just rub the soap in the bag with water to produce a rich later, then rub directly on your skin. You can rinse off the surface of the lather with water after using it, and then hang the soap saver exfoliating bag in a ventilated place.
