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 week agoHi Pauline!
Love that you see them as a classic! 🖤 They really do have that timeless vibe, and I adore that they make you think of Wednesday—such a perfect match for the mood.
🧡🌼 Jace with Cords Club - Kai R.Verified Buyer1 month agoRated 5 out of 5 starsSo Cute!
I love these earrings! I had seen them last year but waited to long to get them because they were sold out. So happy they came back for this year’s Halloween collection! The only downside for me is that they’re bigger than the other Cords Club flat backs I wear so it’s taking a little getting used to. I feel them more, especially when sleeping or when I have my headset on at work. I cannot wear them for a long meeting because it hurts too much. They might be more of a special occasion set than a wear for 3 months set.
CCCords Club1 month agoHi Kai!
So glad you snagged them 🌸✨! We’re thrilled they made it back into this year’s Halloween collection. Since they’re a bit larger than your usual flat backs, it makes sense they’d feel different—especially with headsets or long wear. Many of our customers use statement pieces like these as special occasion sets, while keeping smaller studs for everyday comfort 🌿💫. We’ll keep it in mind as we design future collections.

Its a bit small.
CCCords Club1 month agoHi Lucy! 🪟✨
Thank you for sharing your thoughts on the Enid’s Window Flat Back Stud. 💙 I’m sorry the size felt a little smaller than expected. ⭐ If you would like help with an exchange, please reach out to our customer support team and we’ll be glad to assist. 😊–Hope with Cords Club
