A set of miniature cars with various colors and designs, including a Subaru Impreza, Mazda RX-7, Benz, Hakosuka (Nissan Skyline)? and some Hondas, though I'm not sure of the specific models. I think they were bonus items with canned coffee, but I don't remember much about them. I haven't used them much because they were mostly stored away, but I think they're about 10 years old, so there might be some deterioration due to age. Personally, they don't seem to have faded or cracked much. Except for the black Benz, they are all pull-back cars. The two cars in the second picture are Initial D models. They can be sold individually for 300 yen each.
