Soap Bag
These eco-friendly soap bags are made of sisal, a natural plant fibre. Just pop your soap in the bag and use it as a shower sponge. The lather will come through and the bag itself works as a scrub. Hanging the bag and soap to dry in between uses will also help it last longer.
The soap bag is machine washable and depending on how energetically you scrub, will last for 2 or 3 months.
