A colourful, durable, self-assembly track with balls for children aged 3 and up. The game involves building the track structure yourself, and then releasing the balls through the tunnels. You can follow the pictorial instructions included in the set or create your own tower. Releasing the balls and watching them overcome the winding tunnels gives a lot of joy, calms and soothes. The toy has a positive effect on the development of creativity, imagination and manual skills.
