This appealing, cleverly designed box is the perfect way to start learning colors, with geometric shapes (triangle, circle, square) that your child has to push into the box through the right slot. It also helps children to learn the idea of thickness with 3 sides into which they can insert the pieces at different angles. The box includes 6 colourful pieces (2 triangles, 2 circles and 2 squares) that fit into the box. The box includes a small sliding hatch so the pieces can be easily removed. Great toddler toy. Age 1 & up.
