Wonderfully versatile construction material with great feel. With these components, movement comes into play when the rollers roll across the floor in all directions. Together with our diverse other smaller or larger building games in the appropriate colour, castles, palaces and whole cities are created. The plug-in game promotes motor skills and there is a lot to discover in the variety of colour allocation options. With the help of the wooden wheel (10311, 10312), the large and small construction and plug-in rollers can be stacked up and wonderfully completed. Dimensions: H = 20/40/60/80/100/120/140/160/180/200 mm, diameter 40 mm, 25 pieces in wooden frame
