This soap pouch by Hydrophil is made from 100% biodegradable Sisal. The natural texture helps to produce more foam whilst exfoliating your skin. Sisal is a natural fibre that comes from the Sisal Plant and is stronger and more durable than other natural fibres. Additionally, this soap pouch is also designed for storing bars of soaps and preventing them from going soft and mushy. It is great for keeping ends of soap together and making them into a lather.
