How cool are these “blocks” by Japanese design firm B6 Studio? Designed to look like steel frames, they add a raw, industrial element to the common building toy. Sleek and stunning, yet expertly constructed, they are perfect for rough play or a polished deskscape. B6 is also known for their creative upcycling, winning awards for Bird Call, a sweet toy made from recycled xylophone parts. Check out their website to see all of their fun, creative, and super playful projects.
