Mini 4WD Super XX Chassis Fluorescent Color Chassis Setters This is a combined listing of one bag each of orange, yellow & pink, and green. I am not considering selling them individually. I'm a big fan of the XX chassis and have been building Mini 4WD cars with it, but I have too many chassis now, so I'm selling some of them. Thank you. Please refrain from bidding if you are concerned about the details, as these items are stored at home by a private individual. Unopened, unused.
