This one’s for the sun chasers. A textured starburst meets a dangling pear-cut zirconia perfect for catching light (and compliments).
A Cords Club exclusive, we designed this flat back stud from scratch. We spent months perfecting the size, weight, and look of this gorgeous design!
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud.
Measurements: Post measures at 1/4 inch (6mm) length, with a 4mm disc on back. 18 GA (1mm). Approx. size of front piece is 4.9x10.2mm. Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurement before ordering.
Materials: This is a single push-pin, threadless flat back stud made from ASTM F136 implant grade titanium and enamel. Gold color is 18k gold PVD plated titanium.
Care: These are tarnish-proof and waterproof, with proper care. If you come into contact with chlorine or salt water, cream, lotion, perfumes, etc., rinse in water and gently dry with a lint-free cloth. When not wearing, store in a dry, cool place.

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!

I bought these in gold and silver pairs. SO pretty and sparkly, and they are just the right size. A classy yet whimsical addition to almost any stack! And as always, the comfort of Cords Club's flatback is top notch!
CCCords Club23 seconds agoHi Chelsea 💖,

CCCords Club1 month agoHi Isla!
The Sunburst Flat Back Stud proves that radiance can feel effortless and comfortable. ☀️✨ We're so glad 😀 they're giving you that perfect combination of beauty, quality, and all-day comfort — sounds like they were made for you! Thank you for sharing your excitement and for the 5‑star rating!

- Erica K.Verified Buyer1 month agoRated 5 out of 5 starsSo cute!
Always love a little dangle moment on my flackbacks!
CCCords Club1 month agoHi Erica!
We're so happy you're loving the dangle moment😍! The Sunburst Flat Back Stud really does add that perfect little movement and sparkle—there's something so magical about how those delicate dangles catch the light and add just the right amount of fun to your stack! We love that you appreciate those special details that make flat backs feel extra special while still being so comfortable to wear☀️✨ Thank you so much for the gorgeous 5-star review—we're thrilled you think it's as cute as we do!

- Rachel C.Verified Buyer1 month agoRated 5 out of 5 starsSo cute and fun!
I love these and love the little shimmer they add. The only issue I have with them is that they tend to get caught on things like my hair.
CCCords Club1 month agoHi Rachel!
Thanks so much for the sweet review of the Sunburst Flat Back Stud! We're so happy to hear you love them and that they're adding that perfect little shimmer you were looking for—that's exactly what we hoped for with this design! We totally understand the hair-catching situation though. It can be such a bummer when you love how a piece looks but then have to deal with it getting tangled up throughout the day! The sunburst design definitely has those little rays that can sometimes grab onto hair, especially if you have finer strands or wear your hair down a lot. We really appreciate you sharing that feedback since it helps us understand how our pieces work in real-world wear. So glad you're still loving them despite the occasional snag!
😘~ Elvie with Cords Club
- Brenna H.Verified Buyer4 months agoRated 5 out of 5 starsCute & Dainty
