K’NEX Building Set with 2 Carrying Cases

This K’NEX building set includes lots of pieces and comes with two carrying cases — a red one and a blue one — that fit inside each other. The lid shuts tight so you don’t lose any pieces. This set is not complete but does come with three instruction manuals to give you ideas of what you can build. There are lots of pieces to build all sorts of things but some parts may be missing. Great for hours of fun and imagination!
