Purchased 6 pairs of these earrings for gifts and for myself. I got the 3mm and the 4mm. They’re just as pictured and best part of it was the price. Beautiful quality. Simple and cute! I don’t know about anyone else but my mom taught me to put a tad of clear nail polish so it doesn’t come undone. Although I haven’t had any issues with mine coming undone or anything, I will be doing that to secure them.
