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!

- Natalie D.Verified Buyer4 hours agoRated 5 out of 5 starsSo Pretty
I loved this more than I thought I would. It looks “basic” online, but is so sparkly and pretty irl. I added the titanium spider silk chain as a connector between it and a pearl in my second lobe, and it just looks gorgeous!
CCCords Club2 hours agoHi Natalie,
We're so thrilled you love the Trinity Zirconia Flat Back Stud! ✨ You're absolutely right — sometimes pieces look so different in person, and we're beyond happy this one exceeded your expectations with all that gorgeous sparkle! The way you styled it with the titanium spider silk chain connecting to a pearl in your second lobe sounds absolutely stunning — what a beautiful and creative ear story you've created! We love seeing how our customers make pieces their own with unique styling like that. Thank you for sharing this sweet feedback and for trusting us to be part of your jewelry collection! 🫶🫶🫶🫶🫶🫶

If you've never tried flatbacks and have metal allergies like me, these are the way to go! I leave them in 24/7 and no tarnishing or irritation. Highly recommend!
CCCords Club2 months agoHi Alexandra!

CCCords Club7 months agoHi Katy! That’s wonderful to hear! 💫 Comfort and hypoallergenic materials make all the difference—especially when you never want to take them off. So glad they’re treating your ears kindly and stylishly!🌻 Jace with Cords Club
- Sheena L.Verified Buyer7 months agoRated 3 out of 5 starsCool design but….
I personally don’t think these work as a lower ear lobe earring but an upper ear could work. They feel sharp and catch on hair.
CCCords Club7 months agoHi Sheena L.,
Thank you for taking the time to share your feedback about our Trinity Zirconia Flat Back Stud! We're glad to hear that you think the design is cool and that you can see it working well for upper ear placements. We really appreciate you sharing your honest experience about how these studs feel in your lower lobe and the issues you encountered with them catching on your hair.
Your feedback about how these work in different ear placements is really valuable for us and helps other customers understand where these studs might work best for their setup. It's great insight that the upper ear could be a better spot where the design can shine without the practical issues you experienced in your lobes.
