I’ve worn these adorable rings for three months now, and they are definitely hyper allergenic! I’m very allergic to nickel and these don’t have any in them, no breaking out or itching at all. They are absolutely the cutest things. Wish I’d gotten them in the other two colors as well. I love the silver! And they are the answer for me because I have a horrible fear of having the same freak accident with regular, thick rings, that Jimmy Fallon had when he tripped on a rug and his wedding ring caught on the edge of a table resulting in a “Ring Avulsion Injury” Jimmy warns do not Google this injury because you might throw up! Most of the time, the finger has to be amputated. His ring didn’t “give” and instead, pulled his finger out of its socket! He was in the ICU for days! But these rings are self adjusting, so I don’t see how they could possibly do that if caught on something. They would snap off leaving your finger unharmed. They’re so shiny and sparkly, I hope they stay that way. Another warning! One of the rings I thought, with my poor vision, was a cute little flower, but on closer inspection, found it was two words, total of seven letters, the second word being…”Off!” lol I am SO glad I caught that! Going to have to slip that one off when mixing with certain people. Order these rings. You’re gonna have a lot of fun with them.
