This is a full-sized natural sea sponge (approximately 4"). They are sourced from the beautiful Caribbean by a family-run company that has been in the business for generations. They are hand harvested by divers carefully cutting the sponge, leaving the base behind to promote more efficient re-growth. These are perfect for full-body use. There is something special about a natural sea sponge - the way it absorbs water, the way it feels on your skin, the refreshing feeling it leaves behind from awakening deprived skin cells. Its just different. Dare to be different.
