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 was one othe worst quality pieces I got from cords unfortunately the stone kept falling out. I was able to glue it back in eventually. But not my favorite.

So thrilled you're loving the Opal 3mm Flat Back Studs 💖! We're so glad they're hitting that cute factor for you ✨. Thanks so much for the love!
—☀️ Jace with Cords Club - Celeste B.Verified Buyer1 month agoRated 5 out of 5 starsGorgeous opals!
I am so glad I purchased these. They bring an absolutely stunning luster to my stack. Luminous and bright, they bring a warm glow while also bringing an unexpected pop of color. They are so neutral they go with everything! I wore them to a professional work retreat and got so many compliments from my peers. I love that they are versatile enough to wear to a leadership event and then head out to the pool or lake. They are so comfy to wear I usually forget I have them in. Love love love! Now I need them in a few more sizes so I can do all three lobes in opal from Cords Club! I also got the marquise for my helix once it is fully healed.
CCCords Club1 month agoHi Celeste!
Your review has us absolutely glowing! I love how you described the luminous quality of the opals—they really do have that magical way of bringing warmth and unexpected pops of color while staying so beautifully neutral. And getting compliments at your work retreat? That's the perfect testament to how versatile and stunning they are! It sounds like you've got some amazing plans for your stack with multiple sizes, and the marquise for your helix is going to be such a gorgeous addition once it's healed. Your opal collection is going to be absolutely dreamy!- JM with Cords Club
- Rachel K.Verified Buyer2 months agoRated 4 out of 5 starsNose ring thoughts.
I recently got my nose pierced and purchased this to use as a nose ring. I love the look of it but it is a little bigger than I was imagining it to be, not as petite as I was hoping, but still cute. The 6mm back length is just a little too short for my newly pierced nose, so I switched it out for an 8mm post and that works much better and is really comfortable. So, for other new nose pierced peeps like me- I recommend a little smaller stud, and the 8mm post. I have still been wearing this since I got it though!
CCCords Club2 months agoHi Rachel 🌸,
Thank you so much for your detailed review of the Opal 3mm Flat Back Stud! We're so happy to hear you love the look of it ✨. We completely understand that the opal can appear a bit larger than expected—those 3mm gems do have some beautiful presence! Your feedback about the sizing is really helpful for us and for other customers who are considering this for their nose piercings 💫.
It sounds like you figured out the perfect solution with the 8mm post length for your fresh piercing! That kind of detailed feedback about post length is incredibly valuable for other new nose piercing enthusiasts who might be in the same situation 😊. We're so glad you found a way to make it work comfortably and that you're still loving wearing it!
Thank you for sharing these helpful tips for others with new nose piercings—your experience will definitely help fellow customers make the best choices for their healing journey 🌼.

These go with everything and are just the spring/summer cherry on top of my ear stack! :)
CCCords Club3 months agoHi Avery 🌸
We absolutely love that the Opal 3mm Flat Back Studs are the perfect "spring/summer cherry on top" of your ear stack — what a delightful way to describe them! ✨ There's something so magical about opals and how they catch the light with those beautiful flashes of color, making them the ultimate versatile piece that truly does go with everything 💫. They're such a gorgeous way to add that subtle sparkle and elegance to any ear composition.
Thank you for sharing the love and for choosing Cords Club 💖
