I absolutely love these. Got them in both sizes. I put them on my ears and they're a much better alternative than getting more piercings that take forever to heal. Haven't had any issues with discomfort or the earrings falling off and I've been wearing them to work for several days now. I don't wear my jewelry to bed, so I can't comment on that. Absolutely beautiful product, well made, and I can make them fit my ears however I'd like. I've got the 8mm on the top there and the 10mm on the bottom. If I could fill my entire ears with these cute cuffs I would!
