This key box is ideal for developing the dexterity of the child while having fun. To open the doors and get back the pieces from inside the box, he must choose the correct key corresponding to the lock. Very clever, the back of the transparent box allows you to see the pieces fall and indicates the number and type of cubes to place. The magnetic keychain clings to the handle to avoid losing the keys. This key box contains 6 blocks (1 yellow triangle, 2 blue circles, 3 red squares) and 3 plastic keys.
