Plastic (bakelite?) store display for Vulfix shaving brushes. This sat in a drugstore's shaving goods area for years with no product on it until a friend suggested I ask them for it.
I hadn't thought about scale. It would have been so easy to put a quarter on it!

It's nine inches by nine inches at its tallest and widest points. The compartments are an inch and a half wide, and the plastic on the flat middle part is an eighth of an inch thick.
