Selling these as I no longer need them. These were collected at game centers, etc. They are not McDonald's products. My child loves miniature cars and enjoyed displaying them, but there are some minor scratches. There is no animal odor. I have disinfected them with alcohol, but as I am not a professional, please consider this only if you understand. The 6 cars in the back row move forward when pulled back and released. Functionality confirmed. The 3 in the front row are not the pull-back type.
