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.
