Wooden brain teaser :
The "Himitsu Bako", (which means in Japanese "secret box"), is a unique brain teaser made in Japan according to ancestral know-how dating back to the Edo era.
This simple and pretty box is above all a masterpiece of Japanese craftsmanship ...
We distinguish the boxes by the number of movements necessary for their opening, and their dimension in sun (1 sun = 3 cm approximately).
Equipped with an internal mechanism, this box, once closed, does not reveal any possibility of opening. It will open with a combination of 12 movements that will have to be discovered one after the other.
Once closed, this box leaves no way out and no clues.
Difficult brain teaser.
