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!

CCCords Club1 hour agoHi Elizabeth!
So glad you're loving the Fractal Micro Flat Back Stud!

- Shelby Z.Verified Buyer2 weeks agoRated 5 out of 5 starsAdorable… but sooooo tiny!!!!!
It’s. So. Tiny!!!!! So cute though! Looks just like the pictures!!! The sparkle in person is great! The quality is great!! If you want a teeny tiny precious little gleam of sparkle—get it! Perfect for a cartilage, may be too tiny for most lobes.
CCCords Club2 weeks agoHi Shelby! ✨💎
It's wonderful feedback to know the sparkle looks amazing in person and that the quality is exactly what you were hoping for. You're totally right — it really is a teeny tiny precious little gleam of sparkle, and we love that you're rocking it in your cartilage! 💙 It sounds like it's the perfect fit for where you wanted to wear it. ⭐
