Watching a ball disappear for a second underneath a rainbow arch and reappear, matching each color ball to a corresponding rainbow arch or putting a ball inside and taking it out of the wooden box...little ones love to discover and play with this set of six color wooden balls. As your child grows, the balls can be used to make ever more interesting ball run creations, too. Balls are individually hand dipped in non-toxic stains. Diameter is 1.75". Ages 1+. Linden. Germany
Please note: rainbow arches and boxes are sold separately.
