This set includes a tray featuring a detachable wooden board that serves as a divider. The board has a hole cut into it. The child places the knitball through the hole, causing the ball to vanish from their view as it drops to the other side of the divider. This material helps the child develop hand-eye coordination and the ability to fit objects into openings. Additionally, it introduces the child to the concept of cause and effect, as the toddler must understand what occurs to the ball after it is inserted into the hole.
