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!

- Viktoria D.Verified Buyer5 days agoRated 2 out of 5 starsSo cute. In theory.
I love the idea of these earrings, but they’re so tiny you can’t tell what they are. I expected them to be like 1/4-1/2” in diameter, and they were microscopic. You can see them in relation to my pinky fingernail, and the Zirconia Daisy Flat Back.
CCCords Club4 days agoHi Viktoria!
We totally get it—when you love the design but the size just doesn't deliver the impact you were hoping for! 😅 It sounds like these little blueberries are definitely more on the delicate/subtle side than what you were expecting, especially compared to the Zirconia Daisy. We really appreciate the honest feedback about the sizing, and it's super helpful to know what size range you were looking for. Sometimes those tiny details get lost when you want that cute blueberry design to actually be recognizable! 🫐- JM with Cords Club
- Elizabeth P.Verified Buyer1 week agoRated 5 out of 5 starsTiny blueberry
Cute, very dainty stud. Same size as the single blueberry

CCCords Club1 month agoHi Rachel!
We love how you’ve captured the fun of the mystery palettes—sometimes it’s all about the surprise! 💎 That teal raindrop sounds gorgeous, even if the shape feels a little different from your star. We’re thrilled to hear the quality still shines through and that your studs are staying organized in style. ✨Jace with Cords Club - Mariah K.
