- Post is 1/4 inch (6mm) in length, with a 4mm disc on back.
- Approx. size of gem is 6.1mm x 4.2mm
- Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurement before ordering
Materials: 18K PVD Gold Plated ASTM-F136 Titanium, polished ASTM-F136 Titanium, prong-set 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!

- Kenzie S.Verified Buyer23 hours agoRated 3 out of 5 starsBroke 2 times now
I’ll be honest it’s a cute earring and I want to really like it but it’s now broke 2 times. Where the gem and earring post connects it bends in or snaps with minimal pressure. It’s happened with my original and the replacement I received. I will say costumer service was helpful and easy to get a replacement!
CCCords Club8 hours agoHi Kenzie ✨,
Thank you so much for your feedback! We're so happy to hear you think the Deadly Nightshade Flat Back Stud is cute—we absolutely love this gothic design too! We're really sorry to hear that you've experienced the same breaking issue twice now with the connection point between the gem and post 😭 That must be incredibly frustrating, especially when you want to love the piece so much but keep running into the same durability problem! We totally understand how disappointing that must be when you're dealing with the exact same issue even after getting a replacement. A sturdy connection is so important for flat back studs, and we completely get how this kind of repeated issue can really affect your confidence in the piece even when you love how it looks. We really appreciate you sharing this detailed insight about the specific failure point and that it's happening with minimal pressure—this kind of feedback is so valuable for us and helps us understand how our pieces are performing in real wear situations. We're so glad to hear that our customer service team was helpful and easy to work with for your replacement though!

- CassieVerified Buyer2 months agoRated 5 out of 5 starsStunning!
Love these earrings, they look so cute in. These are an everyday earring in my first lobe holes while my second holes are healing. Only downside is that they turn a lot and I catch myself checking often make sure they are the right way. While doing that I also squeeze them to make sure they’re in because the one time I was turning them the right way I noticed it was coming out a little from the post so I check them all the time now. But they are lovely earrings and I can’t wait for my second holes to heal so I can buy more and change them out!
CCCords Club2 months agoHi Cassie!
Thank you for the amazing review! We're so thrilled that the Deadly Nightshade Flat Back Studs are your perfect everyday go-to while your second holes heal — there's something so special about finding pieces that become your reliable favorites! We totally understand the turning situation with flat backs, and we appreciate you sharing that honest feedback. It sounds like you've found a good routine to keep them secure, and we're just so happy they're bringing you joy every day. We can't wait for your second holes to heal so you can expand your collection and start creating those fun ear stacks! Thanks for being such a wonderful part of our jewelry family! 🖤

- Mikaila C.Verified Buyer2 months agoRated 5 out of 5 starsGood size
These are pretty big stones, I'm wearing them in my 2nd lobe and love them
CCCords Club2 months agoHi Mikaila! 😊
Aw, we're so happy you're loving the size of your Deadly Nightshade studs! 🖤 You're absolutely right—they really are beautifully substantial stones, aren't they? There's something so perfect about having that bold presence in your 2nd lobe, giving you that gorgeous statement piece that still feels so wearable and elegant. The Deadly Nightshade design really shines when it has that perfect size to showcase all those stunning details! We're thrilled they're working so beautifully for your ear setup. Thanks for this lovely review! ✨
😘~ Elvie with Cords Club
