This is part of a set made by Off the Wall Productions. They were a company from Canada that made these awesome sets. This is 2 sided. White on one side and tan on the other. The white side looks like slate, the tan side like stones. They can be used in various methods. The back wall can even be laid horizontal for presenting behind or remaining on. The steps can be utilized as a set of 2 steps or piled on each other for 4 steps. The archway can just be utilized as half an arch given that there is just one wall. It is strong styrofoam kind material that is really durable. It even stands up well for outdoor use.
