Puzzle Box with 666 Parts

The ZITIANYOUBUILD C7649 set contains 666 interlocking plastic bricks designed for builders aged 14 and above. The multi-colour pieces form a themed puzzle box titled "Lock and Key 2: Lock Harder" that encourages spatial reasoning and creative problem-solving. The kit includes a single building-toy set plus PDF instructions for assembly.

100% LEGO-Compatible Bricks

Each brick is moulded from ABS plastic and sized to lock tightly with LEGO and other major-brand elements, so the set integrates directly into existing collections. The tight fit reduces frustration during complex builds but still allows disassembly without tools. PDF instructions replace printed manuals, so a device is needed to follow the steps.

Teen-Focused Creative Building

With 666 parts the set supports medium-scale models, moving mechanisms and decorative detail work suitable for display or play. The piece count limits very large structures or multi-builder group projects, and the 14+ age rating means younger children will need adult assistance. The puzzle-box concept adds a mechanical challenge beyond standard free-form construction.
