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

absolutely love the luna moth. I actually find it to be a little bit big for me but I prefer dainty style and my ears are rather small! I appreciate the detail and the shape, and I love wearing this one in my flat helix to really highlight it.

So glad your sister adores it ✨! That makes the gift even more special — thank you for sharing her joy with us 💛.
—🌼🌿 Jace with Cords Club - Gracie F.Verified Buyer2 weeks agoRated 5 out of 5 starsI absolutely love it
I bought this piece for my outer conch. I wanted a piece specifically for the Halloween fall season, but also had the ability to wear all seasons if I wanted to. This felt like the perfect piece. It sits right in the upper center of my ear and is a perfect statement piece.
CCCords Club2 weeks agoHi Gracie!
The Luna Moth really does have that special seasonal vibe while still being totally wearable year-round—we love that you can rock it through Halloween and beyond. And as a statement piece in that upper center spot, it sounds absolutely stunning 🌿💫!

I love this earring! The design is so cute. I’ve worn it for a couple months and I’ve had no problems with the top falling off or being uncomfortable to sleep on. I usually wear it in my helix or conch piercing and it fits well for me.
CCCords Club2 weeks agoHi N!
So glad this design has become such a favorite for you 🌸
It’s wonderful to hear how comfy it’s been long‑term and that it works perfectly in both your helix and conch piercings 💌✨.
