Petit Collage Where Design Meets Play Our durable nesting and stacking blocks are a modern take on a classic developmental toy. Small hands can practice nesting the blocks inside each other in the right order, and balance them one atop the other to build a tower. Brightly colored illustrations encourage interaction and story-telling. Ready for your ABCs? We've paired each cheerful graphic with its corresponding letter. Made with recycled paper printed with vegetable inks. Conforms to CPSIA, ASTM, and CE standards. 10 nesting blocks feature art on all 5 sides. Completed tower measures nearly 3' tall. Ages 2+.
