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
- Abigail R.YesterdayRated 3 out of 5 starsShort posts
Earrings are cute and seem to be well made. I have sensitive ears and so far they haven’t irritated my ears. The posts though are a bit short. My lobs are thicker than normal I guess so I had to press down quite a bit on the back for the post to poke through so I can thread them. I can’t press them closed all the way because they’ll push into my ear. I worry that they’ll fall out due to not being able to close them all the way. There are a lot of cute earrings on here but I probably won’t buy anymore due to the post length.
CCCords Club1 hour agoHi Abigail!
I'm so glad to hear the earrings haven't irritated your sensitive ears — that's such a relief when you find pieces that work well with your skin! 💕 I totally understand your concern about the post length though, and it sounds frustrating to have to work so hard to get them on securely. Comfort and security are so important when it comes to earrings, especially when you want to wear them worry-free! Thank you for sharing your honest feedback about the fit — it's really helpful to know how they work for different ear types! ✨- JM with Cords Club
- AubreyVerified Buyer2 weeks agoRated 4 out of 5 starsA great one!
I have this style in silver! Overall I like them. Sometimes they feel a little poky due to the shape!
CCCords Club1 week agoHi Aubrey!
So glad to hear you're loving the Mini Opal Hallmark Flat Back Stud in silver! 💕 We totally appreciate the honest feedback about the shape feeling a little poky sometimes — that's super helpful for us to know! Maybe you'd like to consider a longer post, like 8mm would help! Despite that, we're thrilled it's still earning your love as "a great one!" Thanks for being such an awesome part of the Cords Club family! ✨
