Big star plugs

Black plugs with a silver colored star. I must have bought them used and never worn them, they’re still sealed in this pouch, but look scratched and the star side on one looks inexpertly glued on. I also don’t know what size they are, but I tried to show dimensions with the centimeter measuring tape in there. I never stretched past a 0 and haven’t worn big earrings in so long I really couldn’t even guess.
