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!

- AubreyVerified Buyer23 hours agoRated 5 out of 5 starsMy most worn stud!
In the year and a half of owning these in silver, I have worn these more than any other flat back! I love their uniqueness, how they are both feminine and geometric. I wear them stacked with pretty much anything and they are always fun. When I do switch things up I always come back to these!
CCCords Club23 seconds agoHi Aubrey!
Oh wow, a year and a half and they're still your most worn studs — that's the ultimate compliment! 💎 We absolutely love that you appreciate the perfect balance of feminine and geometric in the Hielo design. It sounds like they've become your signature piece, and honestly, we're not surprised they pair so beautifully with everything! The fact that you always come back to them just shows they've truly earned their spot as your go-to favorites. ✨

This is the only place I've seen this kind of half-cog design. I like it
CCCords Club5 months agoHi Phoebe! That’s so awesome to hear—our half-cog design is definitely one of a kind, and we’re thrilled it caught your eye 🖤
🌻 Jace with Cords Club - Erin H.Verified Buyer7 months agoRated 4 out of 5 starsCute little earrings!
I like these earrings a lot. Well made and seem like they will hold up. Took some time getting them in but this is my first pair like this so that’s user error. They are smaller than I anticipated, but I still like them a lot.
CCCords Club7 months agoHi Erin H!
Thank you for your sweet feedback about the Hielo Flat Back Stud! 🌟 We're so happy to hear you're enjoying your first pair of flat back earrings and appreciate their quality. We completely understand that the initial insertion can take some getting used to—it's definitely a different experience from traditional earrings! While we designed these to be delicate and subtle, we understand that the size was smaller than expected. Your feedback about the size and your experience as a first-time flat back wearer is incredibly valuable as we continue to develop our collection. Thanks for being part of the Cords Club community!
