Ok , those items were all called Pocket Jewelry, produced in the late 70's and early 80's. They had 4 models in the early catalogs, but I have seen a couple more than that. In the same category they had Fake tortoise shell and MOP handles. They are cool and collectible, the prices you told me about are very fair in they are new and unused. I have a few you may want to ad if you pick these up. Good Luck !!
