Just what I needed! I'd been wanting to switch from a stud to a hoop for a while. I'd ordered a few other hoops in 14K gold and had allergic reactions to them, which apparently is totally possible even if you aren't usually allergic to gold jewelry? Who knew. So on the hunt for a titanium hoop, which is apparently usually best for piercing allergies, I couldn't find the gauge I wanted (20) in any complete hoop - most of them were the C shaped hoops that don't completely close. Ideally I wanted a hinged hoop, but couldn't find those any smaller than 18g. Enter this bad boy - I was worried about allergies since it's technically just titanium ion plated, but I thought I'd give it a go since it had free returns. It's perfect! It was super easy to put in and close (FOLLOW INSTRUCTIONS, and it's easy). Just pull one side up and one side down (NOT away from each other like Pacman opening his mouth), put it in the piercing, and push them back together. I made sure to open the ring jussstttt enough to get into my piercing, and had no problem getting it back closed. So far, so good on the allergy front (meaning, no adverse reactions yet and it's been in for over 72 hours now).
