What materials are used in the making of the dioramas?
Most dioramas are made of 3/16 foamboard. If you are not familiar with foamboard, it is a sturdy, lightweight material used by architects to construct scale models. While it is durable, it can also be damaged. This is why I do not recommend foamboard dioramas for small children. These are considered fine adult collectibles, as are the car we put in them.
