I did need those little rings, but I don't know what I would do with the rest of the things... well, maybe I could the earring hooks, eventually... *ponder*
If nobody else wants the items, I can give the lot a home in my workbench and put the rings to use. But if anybody else is interested, I'm going to have to order what I need from eBay, anyway, so I'd likely just get the rings with that order, so I'm fine with someone who wants the jewelry parts taking them.
