Physics Tour 14 pounds Plugged There are minor scratches. Please check the photos. (I think I took plenty of photos.) A regular customer at the same center switched to a 14-pound ball, but since it was light, they decided to quit and exchanged it for my ball. I don't have the original box, and I don't know how many ounces it is, so I probably can't answer your questions. It was used for a short time after being plugged and drilled, and has been stored in a locker. Price negotiable. (Used by my wife) Thank you for considering.
