Looking vaguely like a die, a black box with two discs on two faces. Both sets of discs can be turned, but only one set can be turned and moved, before the other set can be moved. When all four discs have been turned and moved, then the lid can be opened. Not too difficult really. But if you weren’t told anything else, would you think you’ve solved the puzzle? If you think you’re finished, you’re wrong, because there is a secret drawer yet to open. The box mechanism is hidden inside the side panels, so you could keep trinkets and stuff inside, and the drawer is just the right size to hide folded banknotes. You may not find it so easy to find... This kit is made from 1/8” birch plywood.
