These blocks were created for parents as concerned as their child's development as the environment they will inherit. They are made from 100-percent renewable bamboo, as is the storage box. They can be decorated by kids using non-toxic Be Block markers. The stencils are made from partially recycled polyester. All the paper and packaging is partially or completely recycled. The set comes with 18 blocks, eight markers, more than 100 stencils and an idea booklet. They're perfect for “people who want to design everything,” Founder Leah Hamilton told TDmonthly. A percentage of the proceeds funds arts education. Watch Be Blocks: Top-5 Video, Toy Fair 2010.
