Piano Puzzle Box

"If you tickle the ivories in just the right way you should be able to open this puzzle box.

But this is more than a simple puzzle box, this puzzle requires the discovery of tools to open it so it does have concepts that will be better suited to the more experienced puzzler but not impossible for a novice.

This puzzle is beautifully made by Jean Claude Constantin in his own workshop in Nuremberg, Germany.  Its made from laser-cut wood with stainless steel screws.  It’s not that it’s fragile but it is delicate and you shouldn’t be too rough with it. Unless otherwise stated it’s generally understood in the mechanical puzzle world that force is not required to complete any puzzle.

Made of laser-cut wood with anodised aluminium posts and screws. The puzzle does contain magnets.
Size: 120mm x 67mm x 65mm    Inside space for a gift: 100mm x 40mm x 25mm
