I'm selling this because I no longer play with it. ☺︎ It works like a Choro-Q: pull it back, and it runs forward when you let go. It was played with by a child, so there are scratches and dirt. Please check the condition in the photos. I will disinfect it with alcohol and pack it with cushioning material. Please purchase with your understanding. If you have any questions about the item, feel free to comment! ♪
