See the KnuckleStrutz building toy sets in action. See the unlimited possibilities of this new construction toy as it used to build motorcycles, helicopters, robots, cars and more.
This is taking model building to a whole new level. The parts move even after you assemble them so my kids love making toys that they can actually interact with and I love the STEM relationship all of Incredibly Interconnectable Toys provide. My kids are getting smarter through play and they don't even fight me to learn!
