See Belgów the multilayered storage for shaving soap. The idea comes from one of the colleagues from Polish traditional shaving forum. The use case scenario is obvious for those who are in the traditional shaving – we’ve got definitely more that one soap at a time.  

I have not seen any similiar thing in the past. So the idea maker is worth encoding into the name of the artifact.
