Wool sea sponges are far superior to synthetic bath sponges for their longevity and soft texture with gentle exfoliation. Our small bulk sponges average 4.5". Harvested by hand off the Gulf of Mexico. Sea sponges are considered a sustainable resource thanks to their ability to regenerate. They are biodegradable and our traditional method of collecting the sponges does not cause any damage to the environment. Wool sea sponges will last for years with proper care. HOW TO USE: When finished bathing, squeeze out the water and keep in a dry place in your bathroom. A sponge will air dry completely and is naturally resistant to bacterial growth.
