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!

- Sierra R.Verified Buyer7 hours agoRated 5 out of 5 starsUgh! Obsessed!!
I knew I’d love these but these exceeded every expectation I’ve ever had😍💚
CCCords Club24 seconds agoHi Sierra!
That "ugh obsessed" energy is exactly what we live for! 😍 We absolutely love when a piece doesn't just meet expectations but completely blows them away – and the Squeeze of Lime Flat Back Studs really do have that special magic, don't they? There's something so refreshing about that perfect pop of lime green that just makes your heart happy. Thank you for that gorgeous 5-star love! ✨💛

- JordanVerified Buyer2 days agoRated 4 out of 5 starsSo cute!!
Let me start by saying that I love these earrings! (I got four) I so badly needed flag backs in my second and third gold cause normal earrings were so uncomfortable and they messed with my ears. The only thing I will say is getting them in is quite difficult. The posts are maybe just a sliver too short and the back of the earring is what needs to go into your ear. My third hole is a normal gauge piercing but I still had difficulty getting them in and it barely stuck out enough to get the front to line up. I had to get assistance due to the angle but that’s not their fault haha overall, very happy and glad I got them in. They are nice and snug. I didn’t have to bend them anymore than they came.
CCCords ClubYesterdayHi Jordan!
Thanks so much for sharing 💕✨! We’re thrilled you love the earrings and that they’re comfy once in place 🌸. We totally understand the snug fit can make insertion a little tricky, but once they’re in, they’re designed to stay secure and cozy 💫. Your feedback means a lot and helps us keep improving!
✨ Jace with Cords Club - Mikayla G.Verified Buyer3 weeks agoRated 5 out of 5 starsLove it

CCCords Club3 weeks agohi Mikayla! 😊

- Jessie S.Verified Buyer1 month agoRated 5 out of 5 starsGinger ale cold enough?
Listen. I *know" it says this is a lime soda earring. However, my love for HR and those hockey boys led to this creation so I'm saying it's green for the ginger ale.
This earring is such a unique shape and I love the pop of color.
CCCords Club1 month agoHi Jessie! 😊
We absolutely love your creative interpretation — ginger ale green for the hockey boys is such a fun way to make this piece your own! That's what makes jewelry so special, it can represent whatever speaks to you. And you're so right about the unique shape and pop of color — the Squeeze of Lime really does add that perfect bright touch to any ear stack! We're thrilled you're loving it and thanks for sharing your sweet review!
😘~ Elvie with Cords Club
