Made of wood and metal by Jean-Claude Constantin, the objective is to open up the box. You can even store your valuables inside. It's not as easy as it might look, which makes it great for the puzzler who likes a well made puzzle box.

Nice looking puzzle. However, I did not get the solution, because it requires so much force that I didn‘t think about it being the solution. Very bad made, you think, no this can‘t be it, it may even destroy the puzzle, but it actually is the solution.l Absolutely not worth the money, don‘t buy it.
