Science Museum Action Reaction marble run bundle - starter, musical and stunt sets

Action Reaction marble run toy by Clementoni, endorsed by the Science Museum. Ages 8-99. One pack new, and the other packs lightly used with a few parts missing and most parts like new. Bundle of three boxes: Starter set - pieces in very good, has both marbles and instructions. Box a little bashed. A few pieces missing. Musical Tracks expansion pack - brand new, never used. All parts. Slight scuffing to outside of box. Stunt Set - pieces in great condition other than the plastic straws which are just straws so easily replaceable. Some pieces still in plastic casing so not yet pushed out and played with. Has both marbles. A few pieces missing- see photo of parts list which I've annotated. A lot of parts to play with and different tracks to make in this bundle! Most pieces very good condition or new but please note there are a small number of pieces missing hence the price. Great Christmas gift for young (or old!) creative builders and engineers.
