3 years & up. Experience the world of Lux through the patented revolutionary snapping hinge technology. Users are able to build structures which curve, bend, move, and fold! Modeled after nature at the molecular level, Lux connects not through sticking or stacking like other building sets, but through linking pieces together. Each durable building block piece connects on all 4 sides allowing for more flexible builds to create toys where any part can move. The Max Freestyle Set includes 330 pieces in 4 colors; black, orange, teal blue, and white. This freestyle set is the perfect set for large construction ideas, small groups, or those experienced with Lux Blox. Building opportunities are endless - free build whatever the imagination desires, or follow the included instructions to build a ferris wheel, scram jet, armored tank, and more!
