Selling a blue box of K'Nex. Contains a mix of parts, including wheels and motors - see pictures. Included in the mix are the parts for two Mech Warrior sets (instructions included). The other instruction booklet is a big book of ideas - not guaranteed to have all the parts, but likely do.
Everything fits in the one big, blue K'Nex box. The smaller boxes are included just for sorting purposes (they also fit in the K'Nex box).
