These toys were played with by my child over 10 years ago. They are made of lightweight plastic and have wheels, so everything except the dolls runs manually. There are no major stains or damage, but there are some minor scratches from use. The ones in the back row are about the same size as a standard Tomica car, or slightly smaller. The ones in the front row are quite small, about half the size of a Tomica car, if that.
