😻5/$15 Banana Republic silver-color studs square hollow

I got these cute studs from Banana Republic. I do not think they are sterling silver, just silver in color. I believe they are hypoallergenic because I usually check for that since I have sensitive ears. However since I no longer have the packaging, I cannot be 100% certain to prove it. Quarter coin included for scale. Not included with purchase. 😻🛍Take items marked 5 for $15 in a bundle and I’ll make offer to reduce the price!
