This is a set of two items: the Keisei Skyliner and the Keisei 3000 series. There are some scratches from use, but they are still in good condition. They run on size D and AA batteries. To provide them in the best possible condition, I have cleaned the exterior and the power unit, and replaced the rubber tires with new ones, so you can use them immediately upon arrival. This is a sale of the current condition, so please check the photos carefully before considering a purchase. Are you looking for these or considering adding to your collection?
