The classic stress relieving toy gets a design update with this colorful set of 20 wooden balls. Specially designed connectors enable interconnected balls to be easily turned and twisted into creative designs. Pop the colored orbs into a 3D circle in rainbow order, construct a pyramid ascending from cool to warm, or just roll the balls into amorphous blobs to stimulate the imagination. Designed by Bernd Liebert of Beli Design in Germany. Materials: Italian FSC-certified beechwood with non-toxic, water-based paints. Recommended for ages 3 to 99 years.
