This set contains a pair of detailed resin mainwheels with crisply molded, seamless and accurate cross tread pattern. You can choose between plain, covered or 6 slot hubs. The inner wheel hub detail is visible through the slots of the outer wheel hub, bringing a whole new level of detail. Makes a quick, easy and very visible upgrade to the Hasegawa, Trumpeter (whose wheels are just plain wrong) and Revell Thunderbolt kits.
