This is Key, machined metal halves that part in one exact order. Hanayama cuts the metal in Japan, and the halves meet along a line you have to find by feel. Taking it apart is the puzzle; putting it back is the second one.

  • Rated level 2 on our six-step ladder, so you know the sit before you start.
  • The solution sheet stays sealed until you ask for it.
  • Comes apart and goes back together — both halves of the puzzle.
  • Pocket-sized, with the weight of a set of keys.
