sisal soap bags.

Composed of the natural sisal fibers from the "agave sisalana" cactus plant--a cousin of the agave plant that we derive tequila from, "agave tequilana" --these sisal soap bags are gently exfoliating, biodegradable, and utilitarian. They function as a soap holder, washcloth, and assist you in reducing waste by allowing you to use every last bit of your soap bars.  

Just insert a soap bar into the pouch, wet it, and work it into a lather.
