Natural Yellow sponges from the sea are processed to produce a bright yellow color. They are firm, durable and farily absorbent. A great bathing sponge. They are collected from the waters of the Florida Keys, Caribbean and the Gulf of Mexico. Sold as either a form or a cut. A form has not been altered from the shape it was found in the ocean. It is more durable and longer lasting. A cut has been "cut" from a larger sponge to fit certain size specifications.
