Our Sea Sponges come straight from Tarpon Springs Sponge Docks. These sponges are harvested right off the gulf coast of Florida. They are a natural yellow sponge. No bleaching. They are pretty soft sponges and very durable when cared for properly. They are firm and absorbent and fairly dense. Each one is 3-4″ making them the perfect size to hold in your hand to bathe. They make great bath and body sponges and facial sponges.
