The intelligent design of this product uses bamboo rings to form very unique building blocks. The distinct angles of the bamboo rings combined with textile edges that act as "grips" create endless possibilities for building exciting shapes and structures. It includes 24 angular bamboo rings and an instruction guide. Hape International Marketing Manager Robin Lehnert told TDmonthly, "The eco-friendly activity helps children develop a sense of spatial awareness, geometry and hand-eye coordination." Launch date: July 2010.
