From the maker:
Loose-woven agave provides just the right amount of scrubbing on the body. Our medium-soft fiber woven bag is suitable for daily exfoliation of the body.
Soap extender: Our fiber exfoliating bag also helps provide a longer life to soaps by letting you use tiny soap scraps (just stuff your scraps in the bag), and helping the soap dry fully between use.
Use it for natural soaps: Natural handmade soaps have a large amount of glycerin (unlike conventional big brand soaps), which makes them moisturizing. Glycerin can pull water from its surroundings, so keeping your soap completely dry between uses is essential.
How to use: Place soap bar or soap scraps in the bag, wet the bag and scrub the body with the bag in the shower. When finished scrubbing, rinse bag lightly and hang to dry where it will dry fully between uses.
Notes: As it's a natural material, agave needs to remain dry between uses to extend its life. Replace every 2-4 months or sanitize by emptying the bag, washing in the washing machine or top rack of the dishwasher, or dipping in vinegar or boiling water.
