I have the pictured sponge, bought a sm piece and now it is all over. Not your typical sponge though, as I have stated before, you could put it in a blender and then leave outside for 3 days in the rain and it would still come back. It was sold as a black sponge, but appears dark blue to me. If you want some PM and I would be happy to send you some, if you pay shipping.
PM sent!
