I purchased 2 boxes and still not enough pieces for my 8yo grandson to build a decent fort.

My kids are very into building “houses”. We bought two sets of these and they have really enjoyed them. The designs are well thought of, with various types of connectors to make sturdy structures as far as imagination leads. Quality is top notch as National Geography products always have been.

Build a rocket, build a Castle just enough pieces for a small cubby. Enjoy with the family

It was a nice idea but when we tried to put it together it was flimsy and would stand up very good and was a challenge to put the pieces together as it kept falling apart. I ended up returning it

Cardboard edges are sharp and cut my daughter toe quite deeply
