The four cars in the back are pull-back cars, which can be run by pulling them back and releasing them. The mini cars in the front row are not pull-back cars. They are in near-new condition, but have been stored at home, so please understand. Please check the condition in the photos. Since this is a personal inspection, there may be oversights. Please purchase only if you understand that these are used items. To prevent replacement, returns and cancellations are generally not accepted after purchase. Thank you for viewing.
