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!

—🌿 Jace with Cords Club - Anna L.Verified Buyer3 months agoRated 5 out of 5 starsChain Reaction Stud
I got this stud to wear my helix. I have not been able to change my earring out from when it was pierced stuff few months ago so I got this stud to put in once I was able to change out the jewelry in that piercing. I just got it changed out two days ago and I love the way. The stud looks in my helix! I would definitely recommend this item.
