Each of the five colorful pins features fascinating textures to feel plus a weighted base that wobbles wonderfully. Fit them into the slots of the big bowl either upside down or right side up, matching the colors as you go. On the bottom of the bowl is a bump that keeps it constantly tilted and inside is hidden a delightful chime. Experiment with balance and movement while keeping the senses enthralled! Little ones can't stop exploring SpinnyPins.
