Retro Vintage Hoop 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 get these to stay on my ears like clip ons but the claps makes me think these may be cufflinks?? I'm not entirely sure*
