The Grimm's Small Rainbow Balls are the perfect size for a variety of marble runs. They bridge the gap between our Grimm's Large Wooden Balls and the Grimm's Small Wooden Marbles. Combined with the new Grimm's Sorting Boards, they are a wonderful 3-D matching puzzle and sorting game for even the littlest ones. With the new Grimm's Building Rings, the balls can grow up into the sky as a balance game. 12 solid wood balls. Materials: maple wood, non-toxic water based color stain, Ø=35 mm
Grimm's Small Rainbow Balls do not come with the cotton bag shown on the first product photo. They come in an environmentally friendly paper bag.
