Build almost anything, from tabletop sculptures to room-sized structures, from ordinary drinking straws and special connectors. The JIX connector has 2 different angles, creating many possibilities. Snap two together for more options. Make basic shapes (triangles, squares), then move on to pyramids and beyond. JIX set (sold separately) comes with 125 connectors, 250 transparent straws, and instructions. Add extra connectors (125) for larger projects. Ages 5 and up.
