Bubble Cross Flat Back Stud

Q: 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!

Q: 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%

Q: 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!

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

Cute and dainty!
Love the detail on the cross. Getting use to inserting them. Will probably order the tool for more ease of it.

This is perfect for a cartillage, if you are looking to wear in your tragus I would get the smaller size !

Dainty 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!

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 😊

Hi 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.
