Buried beneath the surface of the Karakuri Puzzle Box XYK is a unique and bizarre system of wooden panels that guard the entrance to a secret chamber within. The goal, of course, is to reach the center, and 13 special moves are required. Are you up for the challenge? The puzzle is sequential, so all moves must be performed in the correct order before the lid of the box slides open on the 13th step. A true head-scratcher, and it makes a delightfully sneaky storage space after you have cracked the code. Karakuri puzzles are gorgeously constructed by hand from high-quality wood - genuine works-of-art from experts of the craft! This box is co-branded with Master Kenji Nakazato and Kubiya Japan.
