K'nex construction toys (Shrivenham SN6)

Two cases of mixed k'nex parts, plus 2 instruction books. These are several sets combined and I can't guarantee that every part needed for the instruction books are present - these are offered as a wide selection for kids who like being creative and building their own designs. My kids loved these when they were younger and made loads of models, vehicles etc. Manufacturer recommended age is 7+
