ZITIANYOUBUILD MOC-57706 Lock and Key Puzzle Box 379 Pieces

ZITIANYOUBUILD MOC-57706 Puzzle Box

This 379-piece interlocking brick set builds a functional lock-and-key puzzle box designed for adult hobbyists. The model belongs to the Movies, TV & Music theme and arrives with multi-coloured ABS bricks plus a PDF instruction guide. It is marketed as a learning and educational toy that encourages spatial reasoning and creative problem solving. The finished mechanism demonstrates mechanical principles through hands-on assembly.

Brick compatibility and app-enabled limits

The pieces are 100% compatible with LEGO and other major brick brands, allowing builders to integrate the puzzle into existing collections. App-enabled features supplement the PDF instructions but require a compatible smart device not included in the package. The set contains only the 379 bricks supplied; no additional elements, motors or electronic modules are provided. Builders seeking automated functions must source those components separately.

ABS construction and daily handling

Moulded from BPA-free ABS plastic, the bricks feature smooth edges and a tight clutch power that resists accidental separation during play. The varied colours and specialised shapes, including wheels and axles, support repeated disassembly and rebuilding without visible wear. The puzzle box doubles as a display piece and a secure container for small items once completed. It suits home, classroom or makerspace environments where durable, reusable components are valued.
