This is a triple set of Shoulder Accessories & Weapons for Combiner Wars versions of Autobots Prowl, Smokescreen and Bluestreak (either the TFCC Subscription one OR your own custom Bluestreak) to allow them to better resemble their G1 Cartoon/Masterpiece toy appearences. The hand blasters all use 5mm pegs so they are compatible with any figure that has 5mm ports, however the shoulder accessories use special pegs designed just for use with the Combiner Wars Dead End/Streetwise mold, so these accessories would only be compatible with any figure based on this mold's skeleton. These pegs are also intentionally designed to fit a bit loosely to allow for easy removal for transforming the figure(s), as these shoulder accessories are not vehicle mode compatible.
Due to its expensive price, this set has been retired, however - I have now split it into two seperate items, available here:
