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!

Highly Recommended for Sensitive Ears
- Emberlynn S.Verified Buyer2 days agoRated 2 out of 5 starsAdorable but flawed
I love this earring, it's very cute. Unfortunately one of my set had popped out a gem! Luckily, Cord's did honor their warranty and replaced it. The reason for the 2 stars is because my replacement dropped the gem again; I didn't write back into them because I feel bad and I respect that they replaced it the first time! However, this particular one might be a faulty design.
Also, I have a triple helix that I used this earring for and it was a little bulky for my ears but it's the perfect size for a lobe or single helix. LOVE IT, so cute.
(also wrote a previous review for this one but I don't see it, so sorry if this is a repeat)
CCCords Club53 minutes agoHi Emberlynn,
Thank you for your honest feedback about the Hallows Eve Flat Back Stud! We're so glad you love the style—it sounds like it looks amazing in your triple helix setup, even if it's a bit bulky for that spot. We totally get wanting to make it work because you love the piece so much!
We're really sorry to hear that the gem has fallen out again after we sent you a replacement. That's definitely frustrating, and it sounds like there might be an issue with this particular style that we need to look into. We truly appreciate you letting us know, especially since you haven't had problems with your other Cords Club pieces.
Please don't hesitate to reach out to our customer support team again at hello@cordsclub.com—we absolutely want to make this right for you, and your feedback helps us identify potential issues with specific styles. You deserve to enjoy your jewelry worry-free, and we're here to help make that happen.

- Christina2 months agoRated 1 out of 5 stars1 Star
Earrings are ridiculously difficult to secure and then remove. One earring broke the very day I recieved it, with the post breaking clean off as I tried to secure it.
CCCords Club2 months agoHi there,
We’re so sorry to hear about your experience and that one of your earrings broke on the first day. That’s definitely not the experience we want for our customers. Please reach out to our customer support team so we can make this right for you with a replacement or solution. We truly appreciate your feedback.

- chVerified Buyer2 months agoRated 1 out of 5 starsEarring broke day 1
I just recieved my order today and had put the earrings in, with great difficulty. These flatbacks are far more difficult to secure than other flatbacks I've worn previously that screw into place. The bending to secure the earring seems to leave the post excessively weak and prone to snapping off. I managed to put the earrings in, and had decided to swap some of them, where in the process of trying to secure the earring the post broke clean off.
CCCords Club2 months agoHi ch,
We're so sorry to hear about your experience with the Hallows Eve Flat Back Stud! Having the post break clean off on the first day is absolutely not the quality we stand behind, and we completely understand your frustration — especially after dealing with the difficulty of securing the flatback and then having it break when trying to adjust it.
It sounds like you received a defective piece, and the issues you experienced with the securing mechanism definitely aren't normal. Our flatbacks should be secure without being overly difficult to use, and they certainly shouldn't be breaking during normal handling.
Please reach out to us at hello@cordsclub.com so we can make this right for you.
