Mini Safe Puzzle Box 140 Pieces

This interlocking building set contains 140 plastic pieces that assemble into a working safe with a combination mechanism. The MOC design is rated for ages six and up and includes PDF instructions for the build. It is intended for hobbyists who enjoy mechanical puzzles and display models.

100% Compatible With Major Brick Brands

The ABS bricks follow the standard stud-and-tube geometry used by leading building systems, so they connect firmly with existing collections. App-enabled features supplement the physical build but do not replace the printed or PDF instructions. Mixed-brand constructions hold together during play and display.

Working Combination Lock Mechanism

The finished safe uses a multi-digit dial that mechanically engages an internal bolt, allowing the door to open only when the correct sequence is entered. This single functional feature distinguishes the set from static display models and determines whether it meets the buyer's interest in operational puzzle boxes.
