Creative Crafthouse Calibron 12 Impossible Wood Packing Puzzle, Made in USA
- A wooden packing puzzle with a simple goal and a brutal solve: arrange all twelve solid wood pieces into one single square, no gaps and no overlaps. There is exactly one correct solution, and most who try never find it.
- Designed by Theodore Edison in 1933, the youngest son of Thomas Edison and an MIT-trained physicist with more than eighty patents. Our family workshop faithfully reproduces his legendary design for serious solvers today.
- Rated 11 out of 10 on our Impossible Series scale and built for experienced puzzlers, engineers, and collectors who want a real fight. Plan on days or weeks of attempts, and know some solvers never crack it.
- Laser-cut from ash, maple, walnut, and other fine woods, with deep engraved markings and a brief history burned into the frame. Made in our Hudson, Florida workshop as a solid, shelf-worthy heirloom, not a novelty.
- Arrives unsolved with the answer included: the puzzle base, a wood cover, twelve pieces, and a printed instruction and solution sheet. A memorable gift for engineers, mathematicians, collectors, dads, and retirements.
