Frequently Asked Question
We’ve got answers to all your Cords Club questions, from shipping to stacking.
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
Here are a few resources to get you started:
* Review the Flat Back tips and tricks info guide included with your order
* Check out this helpful playlist of how-to videos
* Connect with our customer service team for personalized help
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!
Are your flat backs sold individually? Or in pairs?
Our Flat Backs are sold individually, so make sure to add 2 to your cart if you'd like a pair!
Do I need to buy the flat back applicator, too?
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!

Not going to lie, I created a DIY flatback using the chain! I moved one of my favorite dangles to this chain and now they are flatback ready!
CCCords Club8 hours agoHi Kristin 🌸
We absolutely love the creativity behind your DIY flatback solution! ✨ Moving one of your favorite dangles to the chain to make them flatback ready is such a clever way to customize your jewelry — that's the kind of innovative styling that makes us so excited 💫
🧡🌿 Jace with Cords Club - Jordan4 weeks agoRated 5 out of 5 stars5 Stars
I love my jailbreak stud! I put it in my hidden helix, and it adds the right amount of movement while remaining minimalist.
CCCords Club4 weeks agoHi there!
It’s like a stud that knows how to break free; subtle, sleek, and perfectly balanced with movement.⛓⛓ We’re thrilled it became a favorite. We truly appreciate your 5‑star review! ⭐️

- Liz C.Verified Buyer3 months agoRated 4 out of 5 starsCute, EXTREMELY tiny
Somehow tinier than I was expecting; I wish the chain was just slightly bigger / thicker so that it could stay dangling down better; it’s so light that it has a tendency to get caught up on itself
CCCords Club3 months agoHi Liz!
We're so glad you find it cute! 💎 You bring up such a thoughtful point about the chain—we really appreciate your insight about how the delicate size affects the draping and movement. Your feedback about wanting just a bit more weight for better positioning is incredibly valuable as we continue developing our chain designs. Thank you for giving us 4 stars and for sharing your experience with the piece!

- NatashaVerified Buyer3 months agoRated 5 out of 5 starsOBSESSED
Got these in one of my first ever cords club orders. Was nervous about wearing chain earrings to sleep and long term thinking they would get tangled with themselves or my hair. THEY DON'T!!! I can wear them forever with no trouble. Will definitely pick up another pair in silver as well and maybe multiple sets in the future
CCCords Club3 months agoHi Natasha!
We're absolutely OBSESSED with your review! 🖤✨ It makes us so happy to hear the Jailbreak studs were part of your first Cords Club order and that you've had such an amazing experience with them! Your concern about chain earrings tangling was totally valid, but we're thrilled they've been so comfortable for long-term wear—even sleeping! That's the magic of flat backs 💫 We love that you're already planning to add the silver version to your collection! Multiple sets sounds like the perfect plan 🌸
