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

Hi Elizabeth!

I'm so happy to hear that you're loving the Blueberry Enamel Flat Back Stud for your spring ear styling! 💙 There's something so perfectly sweet about the way you've described it as a "dainty blueberry" — and I absolutely love that you're using it in a mismatched stack with your other blueberry stud! That sounds like such a fun and playful way to create a cohesive yet unique look! ✨ The combination of matching themes with different styles is such a beautiful way to curate your ear, and those little blueberry details must be adding the most adorable pop of color and whimsy to your spring setup! 🫐

Cute but lost
This is the second flat back stud that has gone missing from my ear. The earring was secured properly and I checked on it every day to make sure it was still secured. But one day it was just gone. The other earring I lost I still have but no way to use it since they don’t sell just the backs. Pretty disappointed with the security as I’m also having problems with some hoops I bought.

Hi Melissa,

We're so sorry to hear about the Blueberry Enamel Flat Back Stud going missing from your ear! We totally understand how frustrating it must be to lose not just one, but two flat back studs, especially when you're being so diligent about checking on them daily to make sure they're secure. It's such a bummer when you're doing everything right and the jewelry still doesn't stay put like it should.

And you're absolutely right about the backing situation — it's really disappointing when you lose just one piece and can't use the other earring. That definitely adds to the frustration when you've invested in pieces that you love but can't fully use.

We really appreciate you sharing this feedback about both the flat back studs and the hoops, as it helps us understand where we need to improve our designs and security. Please reach out to us at hello@cordsclub.com so we can sort this out.
