The Rolling Discs Set contains three discs in three different colors with three different sized holes. The set also includes three wooden balls in three different sizes and colors. Place a disc in a Stapelstein® Original (not included) and then simply start rolling! The discs are color-coordinated with the Stapelstein® colors, but can of course be combined as desired. In addition to the rolling game, the discs are also great for building and can be used to create small islands or intermediate levels in buildings. The small additional holes are waiting to be decorated in imaginative play with straws and flowers. The Rolling Discs Sets are the result of a cooperation between GRIMM'S and Stapelstein® and a product that promotes and celebrates open-ended and intuitive play.
