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:

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!

    Super cute!

    I can sleep in these and all of the things. I had to get it replaced (the phone was permanently off the hook) and the customer service was really helpful! My only thing for me (I have tiny ears) is the back could be just a hair smaller in circumference so that they can't touch as much if I lay on them. Would buy again, I think they're cute and kickass.

    You can see the detail of it a lot more in the picture then on my ears so it’s a little disappointing

    Hi Lisa,

    We're sorry to hear the details weren't as noticeable when worn! We appreciate your feedback and understand how that can be disappointing. Thank you for sharing your experience with us!
