Deadly Nightshade Flat Back Stud

Q: 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!

Q: Are your flat backs sold individually? Or in pairs?

Both! Grab a single if you’re mixing and matching, or a pair to save 10%

Q: 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!

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

A Cords Club exclusive, we designed this flat back stud ourselves. We spent months perfecting the size, basket setting, and color for this gorgeous stud!

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

Broke 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!

Hi 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!
