Let the ball roll! Little Dutch's spiral tower provides endless fun. This colourful set consists of 5 subtly coloured parts that your little one can easily stack. Drop the balls one by one onto the top layer and watch them roll and swing down one after the other. The spiral tower contributes to the development of hand-eye coordination and teaches little ones about cause and effect, making it both fun and educational to play. The spiral tower comes standard with 3 light and easy-to-grip balls in different colours that make a sound when moved.
