The knock box Unique 5 Steps

Modernity and tradition

The famous "Knock Box" by Hiroyuki Oka is reinvented in an elegant square format. This unique version showcases the beauty of natural woods on its top panel, while retaining the clever mechanism that made it a success: a first move that isn't a slide, but a secret to be discovered.

The Secret is in the "Knock"

The name of this box is the best clue to unlocking its mystery. To begin the 5-step sequence, you shouldn't try to slide a panel, but perform a special action. It is this unexpected first move that makes this puzzle so original and rewarding. Once the trick is discovered, the box reveals a smooth and logical mechanism, guaranteed by the craftsmanship of its creator.

An Alliance of Precious Woods

This version is distinguished by its refined aesthetics. The top panel is a mosaic of five rare and noble wood species: Rengas, Urushi, Nyatoh, Purple-heart, and Mizuki. This natural palette contrasts beautifully with the traditional Ichimatsu checkerboard pattern that adorns the sides of the box, creating a visually rich collector's piece.
