Holztresor translates “Wooden Safe”, and is a unique version of the famous Rubik’s Cube imagined by the famous Dutch designer Oskar van Devanter (Oskar’s Treasure Chest) and made by Jean-Claude Constantin.

Here, there are no colored plastic pieces, but each of the six faces features a specific wood variety.

Aside from learning to solve the Rubik’s cube using wood grains, this Rubik’s Cube hides within it a secret cavity ideal for containing small gifts. The puzzle can be totally shuffled like a normal Rubik’s Cube, but only when it is solved can its lid pop open to reveal the hiding place inside. The secret compartment inside measures approximately 4 cm in diameter.

A great variation made in laser-cut wood and plastic by Jean-Claude Constantin. Jean-Claude Constantin lives in Germany, where he designs and manufactures many different wood and metal puzzle, as well as magic tricks.

Object Mix up the cube and put it back to the start.
