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!

- Jessie S.Verified Buyer1 month agoRated 5 out of 5 starsRussians love cola
Every ginger ale needs his cola. I could not escape the HR obsession so it led to this.
The piece is such a pretty, subtle color, I love it.
CCCords Club1 month agoHi Jessie! 😊
We love that you couldn't resist the HR obsession — sometimes you just have to give in to what calls to you! And we're so happy you're loving that pretty, subtle color of the Diet Cola Drop. It really is such a perfect shade that goes with everything while still adding that special something to your ear stack! We truly appreciate you taking the time to leave such a wonderful review. Your feedback means the world to us!

- BrittanyVerified Buyer2 months agoRated 3 out of 5 starsNot what I expected
This is such a beautiful stud, but I’m very disappointed because it isn’t the color I expected it to be. Based on the name and the color in the photo I was expecting a deep maroon color. While the color is pretty, it wasn’t what I thought I was buying. It pulls more deep green with a slight purple shift to me and almost looks like a foggy onyx in some lights but definitely not maroon.
CCCords Club2 months agoHi Brittany ✨,
Thank you so much for your feedback! We're so happy to hear you think the Diet Cola Drop Flat Back Stud is beautiful—we absolutely love this design too! We're really sorry to hear the color wasn't what you expected based on the name and photo 😭 We totally understand how disappointing that can be when you're expecting a deep maroon and it pulls more towards deep green with purple shifts instead! Color perception can be so tricky and can really vary depending on lighting and individual perception, but we completely get how the name "Diet Cola" would lead you to expect that rich maroon tone. We really appreciate you sharing this detailed insight about the color difference—this kind of feedback is so valuable for us and helps other customers know what to expect when they're considering this piece. Please reach out to us at hello@cordsclub.com to sort this out.
