Stacking and plugging fun in an arctic look! This stacking tower made of FSC® 100% certified wood motivates even the youngest to sort the six different colored rings according to size and stack them on top of each other. It trains motor skills, hand-eye coordination and an understanding of colors and sizes. The rounded floor, which allows the stacking tower to swing back and forth, thus challenging the children's dexterity, is an additional joy. A movable pin provides additional safety.
