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!

- Nicole C.Verified Buyer8 months agoRated 3 out of 5 starsSo cute but...
Really love these dolphin earrings but one of them has fallen out twice. I haven't had any problems with other designs coming off but this one dolphin refuses to stay in and I'm sure I will lose it soon.
CCCords Club8 months agoHi Nicole C,
Thank you for taking the time to share your feedback about our Dolphin Flat Back Stud. We're so glad to hear that you really love the design - they are pretty adorable! We're sorry to hear that one of the dolphins has fallen out twice and that you're having trouble keeping it secure. That's definitely frustrating, especially when you haven't had this issue with your other designs.
Push-pin flat backs should stay securely in place once properly positioned, and we understand how disappointing it must be to worry about losing a piece you love. This sounds like it could be a fit or quality issue with that particular earring, and we'd love to help get this sorted out for you. Please reach out to us at hello@cordsclub.com so we can make this right and ensure you can enjoy your dolphins without worrying about losing them!
