You would not be able to get me out of the bathroom if it was stocked with bars of Coral Soap. This soap is designed to look more and more like a piece of coral after each use. Say goodbye to soap slivers.

Coral Soap is an interesting concept. Most soaps focus on looking good before their first use. Nobody ever thinks about the end, when the Nintendo soap or Ninja Turtle soap is down to its last sliver. Coral Soap would keep cleanliness interesting until the end.
