This is a new type of secret box, traditional secret boxes have only 4 plates on the surface that move to open the box.
In comparison, all 6 plates move in this new secret box. To open this box a series of individual moves are required. Box I requires six and Box II requires twelve moves. Boxes III and IIII require eighteen moves each, with Box III also requiring different opening methods. The mechanism is 'binary'.
Handmade in Japan using walnut and magnolia, each side measures 8cm.
