The spiral tower from Little Dutch provides endless playtime fun. This colorful set consists of 5 subtly colored parts that your little one can easily stack on top of each other. Drop the balls one by one on 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 with. The spiral tower comes with 3 light and easy-to-grasp balls in different colors that make a sound when moved.
