This is a set of two items: the Tokyo Metro Tozai Line 15000 series and the JR Yokosuka Line E217 series. There are some scratches from use, but I believe they are still in good condition. They run on size AA and AAA batteries. I have cleaned the exterior and the power unit, and replaced the rubber tires with new ones, hoping to deliver them in the best possible condition. You can use them immediately upon arrival. These are sold as-is, so please check the photos carefully before considering a purchase. Are you looking for these, or perhaps for adding to your collection?
