This is an accessory for Leea's learning tower.

Locks and latches - kids love them! not to mention the doors. Not only there is a natural attraction of the child towards mechanisms and doors, but also they are very useful for the development of hand-eye coordination and fine motric skills.  

This board is 40/80 cm (15/30 inch), it is made out of 9 mm thick birch plywood, it is quite massive, it weighs 7 kilograms (15 pounds) and has seven doors with diffenent locks. Doors have different colors and are painted with water based paints. Behind every door there is a blackboard surface that can be written on with chalk.
