I have the Park Hopper pin. (Thin plastic, not metal ) The back is not a point with a clasp that snaps over, like most of our pins have. It is a metal pin back is one of those that has a ring that swivels and the pin moves through the opening. (Not a good explanation, but think you know what I mean.) The situation -- the ring doesn't have an opening! Yes, the notch part swivels in a circle. But there is no opening. Has anyone had a pin with this problem too? Guessing I may just have to take this to a jewelery repair store. Maybe they can remove the pin clasp and replace it. I just want to be careful, since this is plastic. I don't want it snapped in pieces or the paint scratched. Suggestions?
