Your ear stack just aligned and lucky you, this little star flat back stud is the perfect amount of sparkle! It's destiny, written in the stars (and on your ear)!
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud.
Note that this is the same style that came in our 2024 Holiday Advent Calendar.
Measurements:
- 18 GA (1mm)
- Post is 1/4 inch (6mm) in length, with a 4mm disc on back.
- Approx. size of front star is 3.2mm. Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurements before ordering.
Materials: 18K PVD Gold Plated Titanium, Titanium, zirconia

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!

- Emily S.Verified Buyer22 hours agoRated 1 out of 5 starsToo small in every way
Purchased for my 7 year old. I intentionally wanted small stars but these are so tiny that you can’t tell they’re stars at all. Also, the 6mm post is too short to fit all the way through her ears. Other companies include both a 6mm and 8mm post.
CCCords Club9 hours agoHi Emily,
Thank you for sharing your feedback, and we're sorry to hear that the Lucky Star Flat Back Stud didn't work out for your daughter. We understand how disappointing it must be when a piece doesn't meet your expectations, especially when you were looking for something specific.
Every ear's anatomy is different, and we appreciate you letting us know about the sizing concerns with both the star design and the post length. Your feedback is really valuable to us as we think about how we can better serve our customers and their needs.
Please reach out to our customer support team at hello@cordsclub.com with your order details, and we'd love the opportunity to sort this out.
Thank you for giving us a chance.

- Anne S.Verified Buyer3 weeks agoRated 2 out of 5 starsHair keeps getting caught
Really cute earrings but my hair keeps getting caught in the prongs. It gets caught often which is making it annoying to wear daily.
CCCords Club3 weeks agoHi Anne!
Thank you for your honest feedback on the Lucky Star Flat Back Studs! We're so glad you find them cute - the star design really is adorable. However, we're sorry to hear that the prongs are catching your hair and making them frustrating for daily wear. Your feedback about the prong design is really helpful for us to understand how these perform in everyday use. Please feel free to reach out to us at hello@cordsclub.com if you'd like to discuss this further.
