Mechanical 3D Wooden Puzzle Kit

The ROKR LK502 Treasure Box is a laser-cut plywood model that assembles into a working combination safe. It is designed for hobbyists aged 14 and older who enjoy hands-on construction and mechanical puzzles. No glue is needed because the precision-cut parts interlock tightly, though light sanding may help the fit.

Fixed Three-Digit Combination Mechanism

During assembly you choose a three-digit code from the 1,000 possible combinations between 000 and 999, but 190 of those codes cannot be set. Once the build is finished the password is permanent and cannot be changed, so the chosen number must be recorded carefully. The detailed English manual guides the setting process step by step.

Hidden Storage With Dual Opening Actions

Turning the rear key raises an inner tray that can hold small items such as a ring, while rotating the top gear opens a flower-like compartment on the lid. Both movements are purely mechanical and rely on the accuracy of the assembled wooden gears and levers. The finished box serves as a decorative secret-keeping device rather than a high-security safe.
