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
- Lauren A. E.Verified Buyer16 hours agoRated 3 out of 5 starsLovely, but…
This stud is stunning - the opal is a great size and the tiny sparkle is perfect. The only issue is that the prongs that hold the opal are consistently snagging my pillowcase every time I turn over from the side that the earring is on. So I wake up every time I turn over. As much as I love the earring, and I will be keeping it to wear from time to time, I’m on the search for another stud that I can wear 24/7 as a default. I just can’t sleep with this thing, no matter how cute it is.
CCCords Club23 seconds agoHi Lauren,
Thank you so much for your feedback about the Tortuga Flat Back Stud! We're so happy to hear you find it stunning and that you love the opal size and sparkle—that really means a lot to us.
We're really sorry to hear about the snagging issues with your pillowcase though. Having the prongs catch and wake you up every time you turn over sounds incredibly frustrating, especially when you want to wear it 24/7. We completely understand how that would make it difficult to sleep comfortably, no matter how much you love the design.
Your feedback about the prong setting and how it affects sleep comfort is really valuable to us. We know how important it is for our customers to find pieces they can wear around the clock without any discomfort or disruption.
We're glad to hear you'll still be keeping it for occasional wear when you want that extra sparkle! Thank you for taking the time to share your honest experience and for the 3-star rating. Your insights about real-world wearability help us understand how our designs work for different lifestyles. ✨

- Amanda5 months agoRated 5 out of 5 stars5 Stars
Very cute! I added the Tortuga to a trio of opal studs in my lobes, its the perfect mid-size between the micro and 4mm opal studs. The little gem stone adds a bit of panache to the mix.
CCCords Club5 months agoHI Amanda!
Thank you for the great feedback! Happy to hear the Tortuga Stud pairs so well with your micro and 4mm opals. –Hope with Cords Club
- Olivia5 months agoRated 4 out of 5 stars4 Stars
Super cute but its so tiny and hard to insert backing into ear first and then to try to line the earring into the backing. Overall I love it!
CCCords Club5 months agoHi Olivia!
Thank you for the great feedback! Glad the Tortuga Stud is bringing you joy, even if it takes a little patience. –Hope with Cords Club
- Hannah M.Verified Buyer10 months agoRated 5 out of 5 starsComfy!
I love the opal and gem combo and got these studs for my second piercing to match the plot twist hoops! Very comfy to sleep in too.
CCCords Club10 months agoHi Hannah! That’s dreamy styling with a twist—literally! 💖 We’re loving the opal and gem glow, especially paired with the Plot Twist hoops for that perfect second-piercing statement. And comfy enough for sweet dreams? That’s sparkle done right. ✨🌻 Jace with Cords Club
- Nicole S.Verified Buyer11 months agoRated 5 out of 5 starsTortuga <3
I am a lover of all things turtle, so when I saw these, I just had to have them. They are so cute and have a small profile, so they don't snag on anything!
CCCords Club11 months agoHi Nicole! That sounds absolutely adorable! 🐢✨ Turtle-themed jewelry is such a charming way to show love for these amazing creatures, and it’s great that the design is both cute and practical. Having a small profile that doesn’t snag on anything makes them even better for everyday wear! Sounds like a perfect addition to your collection. 🌻 Jace with Cords Club
