I received a a box of dollhouse materials and tools and this was in it but I have no idea what it is or what it was being used for. It’s a magnetic metal tray with four holes in the sides, and there are a number of metal square pieces with holes, some with magnetic and some without. There are also those rods and that tool that looks like the drill bits can be inserted into. Any help or information would be appreciated!
