3DuxDesign Construction Set with 60 Clips That fit Cardboard- Perfect for Building and Open Ended Creative Play in Home and STEM and STEAM Learning at School, Ages 4+

Not sure that this little container is worth $25. You've got to be kidding me? Nothing like I thought it was. It fits in the palm of my hand!! We'll soon find ot how well they work once my grandson starts building with them. :/

The brilliant thing about these 3Dux connectors is that they're designed to fit pretty much any cardboard-like materials (I knew they worked with other 3Dux cardboard modeling sets you can get separately, but apparently they also fit household cardboard pieces and more!). So it's shocking how this portable little jar just opens up the world to students—suddenly everything is a potential building material! Its compact size makes it easy to travel with, and you have just enough connectors without expecting an inevitable mess.

Photos suggest this is a fort-sized kit, but really it's palm sized.
