* A truly customizable mechanical lock
The internal mechanism consists of three layers with grooved gears. The scale must be rotated in the correct sequence to align with the grooves before unlocking the internal latch and pulling out the drawer. It also offers an entertaining challenge of solving puzzles and unlocking.
* Built-in storage space
The interior of the drawer is hollow, allowing for the storage of small valuables such as coins, small jewelry, mini figurines, USB drives, notes, and loose change. It serves as both a building block model and a practical storage box.
* STEAM mechanical science teaching set
The assembly process fully disassembles the gear transmission structure of the lock. The accompanying manual comes with mechanical principle diagrams, enabling intuitive learning of lock transmission and gear meshing knowledge. It belongs to an educational building block category.
