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!

Highly Recommended for Sensitive Ears
- Chloe C.Verified Buyer2 days agoRated 3 out of 5 starsDisappointed with how the pair looks.
I bought this earring has a pair to wear as lobe piercings. The earrings are decent, cute, and don’t cause any irritation. However, I find it annoying that as a pair the moons face the same direction making it so one ear has it facing towards my face and the other ear has it facing away from my face. Because the moons have the star chain attached you can’t simply twist the moon to face any direction. It’s a personal preference but I find that one stack looks great and the other looks off. Just something to consider when buying a pair vs a single and depending on what side you plan to wear it on.
Personally think the right ear looks best as a stack where the moon faces towards my face vs the left where the moon and star faces away from my face and throws the stack off.
CCCords Club22 seconds agoHi Chloe.
Thank you for sharing your review. We're glad to hear that the Hang the Moon Flat Back Stud is comfortable and cute to wear. We totally understand your feedback about the directional placement of the moons when wearing them as a pair — that's really helpful insight for us to hear, and we appreciate you taking the time to explain how it affects the overall look of your stacks.
Your thoughtful note about considering which side works best for you is something we'll keep in mind as we think about future designs. Thanks so much for being part of our community!

- Emily J.Verified Buyer1 month agoRated 5 out of 5 starsSweet and celestial
This piece is simple but not in a bad way. It would tie together a space-themed ear beautifully. The chain is a nice touch and the perfect length.
CCCords Club1 month agoHi Emily!
So dreamy 🌙✨! I love how you described it — simple yet celestial, with the chain adding just the right touch. It sounds like it really ties together a space‑themed ear stack beautifully 💫. Thank you for sharing your thoughts, it’s wonderful to hear how you’d style it!
