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!

This is perfect for a cartillage, if you are looking to wear in your tragus I would get the smaller size !
CCCords Club22 seconds agoHi Jeannette!
The Bubble Cross Flat Back Stud proves that finding the perfect fit for every piercing is an art! 💎 We're so glad it's working beautifully in your cartilage and appreciate your helpful sizing tip for tragus piercings. Your 5‑star rating means the world to us! ⭐️

- Natalie D.Verified Buyer3 weeks agoRated 5 out of 5 starsDainty and Cute
Dainty and cute! I was torn between this and the normal cross, and chose this one thinking the bubble texture would be cohesive with the texture of other studs in my ears (I have 3 lobe piercings per ear). It goes very well and is the perfect size!
CCCords Club3 weeks agoHi Natalie!
We're so happy to hear you love how dainty and cute they are! It sounds like you made the perfect choice—the bubble texture creating that cohesive look across all your lobe piercings must look absolutely beautiful. Thank you for sharing how well they work with your ear setup! ✨

CCCords Club5 months agoHi Valerie!
Aww, we're so happy the Bubble Cross ✝️✝️ Flat Back Stud has earned a spot as one of your favorites! ✨ There's something so sweet and versatile about that bubble cross design — it's got just the right amount of detail to be special while still being perfectly wearable every day. Thanks for the lovely review and for letting us be part of your jewelry collection!

- Piper6 months agoRated 3 out of 5 stars3 Stars
Alot tinier than I thought and hard to put in if you have long nails. Its hard to grip and put the post in the flat back. I see a tool you offer but it only helps to put peircing in the hole but not actually put the earring in the flat back. Other than that happy with purchase 😊
CCCords Club6 months agoHi there,
Thanks so much for sharing your experience! You're definitely not alone—flat backs can be a bit tricky at first, especially with longer nails. We hear you on the tool, and we’re always looking for ways to improve ease of use. If you ever need a hand or have questions, feel free to reach out to our customer support team—we’re happy to help. So glad to hear you're happy with the purchase overall.

It was a waste of money it's too small for me to handle
CCCords Club1 year agoHey there!
I’m sorry to hear that the Bubble Cross Flat Back Studs weren't the right fit for you. We always want our customers to be satisfied with their purchases, and it’s disappointing to hear you weren't happy with the jewelry. We try our best to show the size in the listing photos and include the measurements in the description to avoid this. If you're looking for something larger or different, we’re here to help you find a better match!
Feel free to reach out if you’d like to discuss further at hello@cordsclub.com.
