This 530 piece jigsaw assembles into a freestanding sphere of the world that requires no interior support, creating a 9.5'' diameter 3D jigsaw puzzle. What about the last piece? The 'North Pole' piece has a trap door cut into it. When the rest of the puzzle is complete, this trap door can be opened, allowing the last piece to snap into place and then resealed. It's utterly amazing! |
