A classic developmental toy, now made entirely from Earth-friendly, recycled materials! Ten sturdy boxes to stack, build, and nest feature beautiful illustrations and enriching content for hours of fun and learning. Kids will love stacking the boxes to build a tower with tons to explore from every angle, then nesting them back inside one another. Kids will discover a different early-learning concept on each side! Learning letters, numbers, shapes, colors and baby animals has never been so fun and easy! Boxes store perfectly in the carry-along storage case. Tower stands nearly 3 feet tall!
