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:

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?

Both! Grab a single if you’re mixing and matching, or a pair to save 10%

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!

    Loved them! One broke within a month

    I will say, love these earrings. Wore them for about a week straight and then one of the posts snapped off the front while sleeping.

    Pretty but pokey

    I love how these look. Not the most comfortable to sleep in if you’re a side sleeper but it’s perfect if you’re going for a lunar theme.

    Hi Traci,

    Thank you so much for the 5-star review! We're really glad you're loving how the Lunar Phase Flat Back Studs look—that lunar theme is definitely a vibe. We totally hear you on the comfort side sleeping as a side sleeper though, and we appreciate you sharing that feedback with us. Flat backs can definitely feel a bit different when you're resting on that side, so we get it!

    Hi Eli ✨,

    Thank you so much for your feedback! We're so happy to hear you think the Lunar Phase Flat Back Stud is super cute—we absolutely love this celestial design too! It sounds like you really enjoyed wearing it daily, which is exactly what we love to hear! We're sorry to hear that it lost its sparkle and became dull after about 8 months of daily wear though 😊 We totally understand how disappointing that can be when you love a piece so much that you wear it every day! Daily wear can definitely be tough on jewelry, and we completely get how losing that initial sparkle affects the overall look you fell in love with. We really appreciate you sharing this insight about how it held up over time with consistent wear—this kind of long-term feedback is so valuable for us and helps other customers know what to expect with daily use too! Even though the sparkle faded, we're glad you still found it cute enough to give it 4 stars 💖. Our earrings are backed with 365 warranty, if it's within a year, feel free to reach out our customer service team, hello@cordsclub.com for the next steps to claim the warranty. Thanks for taking the time to share your honest thoughts with us!

    😘~ Elvie with Cords Club
