From the 2012 Karakuri Creation Group 4th design contest.A great looking, fun, beginner puzzle box.This is a work that came out from the 4th design contest.

Wooden gears are used as the mechanism. The glass (plastic) cover will not open. Which part is the real cover? And how do you open it?PayPal fees and shipping paid by winner.

This put together puzzle blurs the line between packing and interlocking puzzles. With a level 4.4.17 solution, there’s some dastardly trickiness going on that will surprise you. The interaction between the first two pieces is quite surprising, replete with dead ends and other surprises.
