Every budding architect, engineer, and artist should have access to this unique precision-cut building toy. 72 vibrant modular blocks fit into each other like puzzle pieces to create airy, architectural structures. Limitless opportunities for older children to test their spatial, problem-solving, and balancing skills. Very young children, who can’t resist the translucent colors and appealing feel of the wood, can sort pieces by color or shape and help fit the cubes together. A “green” product, constructed of highly-renewable rubber wood. Wooden cubes range from 1¾" to 3" square; rectangular rods are 3" long. Twig™ blocks are a Parents’ Choice Gold Award.
