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

I ordered the set and the stud broke off the back of the phone piece. I messaged you guys and you kindly sent me a new one, but it has now broken again.
CCCords Club3 hours agoHi Madison,
We're really sorry to hear that the stud broke again after we sent you a replacement. We understand how frustrating that must be, especially after already experiencing this issue once. Thank you for giving us another chance, and we truly appreciate you letting us know about what happened.
We'd like to help make this right. Please reach out to our Customer Support team so we can look into this further and see what we can do for you.

SO so cute!
- Elizabeth R.Verified Buyer4 days agoRated 5 out of 5 starsSuper cute!
I can sleep in these and all of the things. I had to get it replaced (the phone was permanently off the hook) and the customer service was really helpful! My only thing for me (I have tiny ears) is the back could be just a hair smaller in circumference so that they can't touch as much if I lay on them. Would buy again, I think they're cute and kickass.
CCCords Club22 seconds agoHi Elizabeth!
So glad you're loving the Haunted Hotline Duo 💌🌿! That's awesome that you can sleep in them comfortably — and we really appreciate you letting us know about the replacement process. So happy our customer service team could help you out with that ✨! We hear you on the fit preferences, and we love that feedback about the back circumference. Thanks so much for the 5 star rating, and we're thrilled these studs are checking all your boxes 💙🌸!

You can see the detail of it a lot more in the picture then on my ears so it’s a little disappointing
CCCords Club1 week agoHi Lisa,
We're sorry to hear the details weren't as noticeable when worn! We appreciate your feedback and understand how that can be disappointing. Thank you for sharing your experience with us!
