The black-based items are mostly 10cm in size. Based on the size, the ones with bases are likely 1/43 scale model cars. The others are model cars about 12cm in size. These were found while cleaning out my grandfather's house, so I don't know much about model cars. I can only ask you to judge from the photos, but since they were in a display case, I think they are relatively clean. There are no boxes they came in. No individual sales. Retro cars
