This is a used Red Speed Trak Slot Car Racing Trigger Wired Toy Hobby. It has not been tested (untested). I do not hear anything rattling inside and it doesn’t smell burned. What you see in the photos is what you will be receiving. Should you have any questions or or would like more photos please let me know. There are scratches and scuffs so, please review the photos for any wear and tear. Thank you!
