DESCRIPTION
The onyx tone brings mystery. The marquise shape brings edge. Together, they make a flat back stud that’s anything but boring.

- Post is 1/4 inch (6mm) in length, with a 4mm disc on back.
- Approx. size of gem is 4.99mm x 3mm
- Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurement before ordering

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!

- Kelsie h. l.Verified Buyer5 days agoRated 5 out of 5 starsEdgy
I love the claps around this. It gives it a different look and vibe.
CCCords Club21 seconds agoHi Kelsie! We're so glad you love the edgy vibe the prong setting brings! 💎 It's wonderful to hear how the unique claps give it that different look you're loving. ✨Jace with Cords Club
- Ana A.Verified Buyer2 weeks agoRated 4 out of 5 starsVery cute but smaller than expected
These earring are very cute but ed than expected. I didn’t pay attention to all the pics. Still very cute though. I have other flat backs that twist on and some have fallen off. These don’t since they are push ins.
CCCords Club2 weeks agoHi Ana ✨,
Thank you so much for your feedback! We're so happy to hear you think the Prong-Set Marquise Flat Back Stud - Onyx is very cute—we absolutely love this elegant design too! We totally understand what you mean about the size being smaller than expected, and we completely get how easy it is to miss those sizing details in the photos! Size can really make a difference in how a piece looks once you have it in hand, and we appreciate you being honest about that. We're so glad to hear you're happy with the push-in closure system and that it's giving you that extra security compared to twist-on flat backs! There's nothing worse than losing an earring because the closure wasn't secure enough, so we're thrilled the push-in mechanism is working well for you and giving you that peace of mind. We really appreciate you sharing this detailed insight about both the size and the closure experience—this kind of feedback is so valuable for us and helps other customers know what to expect when they're considering this piece.
Thanks for taking the time to share your honest thoughts with us—it means so much! 💖
😘~ Elvie with Cords Club
- DanielleVerified Buyer2 months agoRated 2 out of 5 starsBeautiful BUT…
I absolutely love the look of this stud, however… it gets snagged on absolutely everything. Blankets, pillow cases, hoods, hair, you name it. Had to take it out because it was causing irritation getting caught so frequently.
CCCords Club2 months agoHi Danielle!
We're so glad you love the look of the marquise onyx stud - it really is a gorgeous piece! But we totally understand your frustration with the snagging issue. The prong setting does create those little edges that can catch on fabrics and hair, which is definitely not ideal for everyday comfort.
Our pieces are made for sensitive ears, and we are so sorry for the irritation. However, everyone's allergies are unique, and no two sensitive ears are alike. We test our metals and have an extremely high success rate for sensitive-ear approval; however, it sounds like these didn't work for yours. We're so sorry to hear that. Please contact our support team so we can help make this right for you by helping with a quick return of your pieces.
Thanks for taking the time to let us know about your experience!

- Becky W.Verified Buyer2 months agoRated 3 out of 5 starsIt was okay
I put this in my tragus piercing but had to take it out shorty (a couple of days) as it was hurting my ear and becoming sore. I have really sensitive ears and mostly on the earlobes but guess it’s with my tragus too. So I could have been user error and me being a dummy to think I could wear it there. It was so cute for the time tho!
CCCords Club2 months agoHi Becky!
Thanks for the honest review and for giving it a try! We totally understand that sensitive ears can be tricky, especially with cartilage piercings like the tragus. It's definitely not user error on your part - everyone's ears are different, and what works for one person might not work for another. We're glad you thought it was cute for the time you could wear it, though! Please reach out to us at hello@cordsclub.com so we can sort this out.

The earring looks delicate and beautiful
CCCords Club3 months agoHi Alexandra!
Delicate and beautiful is exactly what we were going for with the Prong-Set Marquise! 🖤✨ The marquise cut really gives it that elegant, refined look while still keeping that gorgeous onyx drama we love so much. We're so thrilled it's hitting all the right notes for you — that delicate vibe paired with the stunning onyx is just chef's kiss perfect! Thanks for such a lovely review!
😘~ Elvie with Cords Club 🖤🎃
