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!

- Mareike T.Verified BuyerYesterdayRated 3 out of 5 starsCute but not durable
This stud is so pretty and I love the concept but sadly when I originally ordered it, it arrived broken and then the free replacement ended up breaking the same way when I was putting it in the first time :(
This design might make for a better hoop charm than stud!
CCCords Club26 seconds agoHi Mareike,
Thank you so much for sharing your feedback on the Luna Moth Flat Back Stud. We're really glad you love the design, and we're truly sorry to hear that both your original stud and the replacement broke during wear and installation. That's definitely not the experience we want for our customers, and we understand how frustrating that must be.
We take this seriously and would love to make this right for you. This type of issue is covered under our 365-day warranty, and we'd be happy to help. Please reach out to our customer support team at hello@cordsclub.com so we can take a closer look at what happened and assist you further.
We appreciate you taking the time to share your thoughts with us.
