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

With the Building Rings, the balls can grow up into the sky as a balance game. 12 solid wood balls.
