Retro Vintage Clip On Earrings ? Cufflinks ? 80s

Found an old stash of my grandmother's clip on earrings! Back in the days where only "loose women" had their ears pierced (😜), these clip ons were all the rage! No idea what they're made of but great fun for kids and adults alike. Bundle and make an offer! 😊 *I was able to make these work as clip on earrings but they might be cufflinks....not entirely sure?*
