Vintage 1980s clip earrings fan shaped blue and similar items

This is a pair of vintage 1980s clip earrings, dark blue enamel with gold-tone metal in a fan shape. I don't know the brand or manufacturer as there are no markings on them. They measure about 1.25" X 0.875" (an inch and a quarter by 7/8 of an inch). In excellent used condition, the spring mechanism on the clip works fine; they may show a couple tiny spots of wear on the blue part, but nothing you're going to see unless you're inspecting closely. Asking $4.00 obo. Everything I have listed for sale is "or best offer", so feel free to make an offer. ~~~~~ ALL ITEMS ARE AVAILABLE FOR LOCAL PICKUP. I sell a huge variety of stuff to supplement my income and help me put the last of my kids through college. Some items come from flea markets or estate sales, and some come from around our home, but many items come to me from my extended family of hardcore hoarders. So, the variety really can be vast and unpredictable. Please check back often, because you really never know what I will have from one day to the next! Thanks for visiting and have a great day!
