This work was designed as a Christmas present for 2012.
This is a seven move Secret Box. The feature is that both sides of the box move in a process to solve the box. As for most Secret boxes that are sold in Hakone and other areas, only one side moves. More work is needed to make Secret Boxes where both sides move. In any case, the puzzle becomes more interesting. This box was made beautifully with Yosegi checkered patterns.
