The colorful board teaches children how to use different types of locks. The toy consists of a piece with individual moving parts. Specifically, it contains a wooden colored base, a door, and two windows of different colors and designs that close with different types of locks. Each opening offers the opportunity to practice a different skill. The door teaches the child to open and close a latch, the square window teaches to open and close the bolt, and the round window to use the hook. 

With this toy, children develop and practice fine motor skills in combination with hand-eye coordination. At the same time, it allows children to try to combine the toy with small daily achievements and to become familiar with the use of locks.
