Q: What size are the flat back earrings?

Cords Club's Flat Backs are 18 gauge and come with a 6mm long Flat Back post.A 6mm post is a great length for most people, so we'd recommend starting there! We do also have a range of other sizes available and sold separately. If you have questions about sizing, we'd love to help!

Q: Are your flat backs sold individually? Or in pairs?

Both! Grab a single if you’re mixing and matching, or a pair to save 10%

Our Flat Back Applicator is a great tool but it's not necessary! The Flat Back Applicator is designed to help make the process of changing your flat backs faster and easier, but you can definitely change your earrings without one. The choice is totally up to you!

I'm new to flat backs. What is the most important thing for me to know?

The first thing you'll want to learn is how to keep your Flat Backs nice and secure. Just like you'd tie your running shoes to make sure they stay on your feet for a run, you'll need to adjust your Flat Backs to keep them in place, too!

But don't worry! It's an easy peasy process, and we'll help you through the learning curve. <3

Perfect earring for a high cartilage piercing
I have this in white stone as well. It fits so well as a high ear cartilage piercing. I will definitely be getting these in more colors in the future. So comfortable!

One of my favorite pieces!
I have owned this piece for a bot more than a year, and I still love it. I think this might be my favorite piece for daily wear and for sleep for my helix. It looks great, and for me specifically, the shape is very comfortable as a side sleeper. It might not be that way for everyone, but this is my go to piece whenever my helix gets irritated. I have worn it in the shower and while playing sports, and I haven't noticed any discoloration or wear.

What dreams are made of
My biggest dilemma with these earrings was first to get them in clear or onyx? Followed by gold or titanium? I opted for the onyx in titanium to stack with the micro triangle stuff in onyx and the black dahlia earrings. It is everything I hoped it would be! At first it felt heaving in my cartilage piercing but after about 5 minutes I didn’t notice it anymore! I have had it in about 5 days in a row and been able to sleep in it with no discomfort. The first night I slept in it I did lay on my ear and fold the skin weird that I noticed it. But it hasn’t gotten caught on anything even my glasses! There’s no way you could regret trying this style no matter what metal you prefer or stone color

Hello Victoria🌸,

We're absolutely thrilled to hear these Onyx Ear Climbers are everything you hoped they'd be! ✨ Your stack with the micro triangle studs and Black Dahlia earrings sounds like such a stunning combination 🖤. It's wonderful that after the initial few minutes of adjustment, they've been so comfortable you can even sleep in them! We love knowing they haven't gotten caught on your glasses either — that's always such a relief with climber styles 💫. Thanks for sharing your experience and encouraging others to try this style — your enthusiasm is contagious! 🌟
