This pretty and sophisticated box is perfect for introducing colors and shapes (triangle, circle, rectangle) that your child must insert through the correct opening in the box. Thanks to the 3 sides, where the pieces must be inserted at different angles, your child can also become familiar with the concept of thickness. The box contains 6 colorful shape pieces (2 triangles, 2 circles, and 2 rectangles) that can be stored inside. A small sliding flap allows the box to be opened for easy removal of the shape pieces.
