The center piece can only slide up and down. Pieces cannot fall out through the transparent top plate. More assignments on the back of the puzzle. Material MDF.
The nummers are covered with transparent foil. You can slide without damage.
I discovered this online. I made a copy in the original colors. Not out of cardboard, but on transparent film. I also made a box that was as original as possible. Unfortunately, the original edition comes with a solution.Place the pieces perfectly on top of each other and find the rabbit.
