This wooden box is from Lovevery’s Thinker Play Kit, designed for months 11-12. It has two compartments and a sliding wooden lid that moves from side to side. Drop the ball in the hole and watch it disappear. Then slide the box’s lid and see it appear again. Magic! Supports hand and finger strength and problem-solving skills as they work to manipulate the ball and box lid. The card with play ideas and developmental info for parents is included.
