These small solid wooden balls are the perfect size for a variety of marble runs. They bridge the gap between our large wooden balls (10239, 10238, 93120) and the small wooden marbles (10225). Combined with the sorting boards (10576, 10577), they are a wonderful 3-D matching puzzle and sorting game for even the littlest ones.

With the Building Rings (10163, 10164), 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, diameter =35 mm.
