We call these a sponge, what they really are is a type of cloth made from Bamboo fiber, that's been folder and sewn into a traditional sponge shape. These clothes take the place of the traditional kitchen sponge (which are very un-hygienic, usually filled with germs and all kinds of icky things).
These cloths are super absorbent. They can absorb up to 4 times as much liquid as a cotton towel. Luxurious Silky Soft, they are also called Cashmere Towel . Made from 100% Organic bamboo, they are Eco-Friendly. Naturally anti-bacteria, anti-fungal and odor resistant.
Avoid using bleach or fabric softener during laundry.
