Solar Halo Flat Back Stud - Sapphire

Q: 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!

Q: 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%

Q: 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!

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

Gorgeous
I wear these in my thirds and they are so cute and dainty with the perfect pop of color. With the Celestial 6 or 8 mm Hoops and the Blue Hour Titanium Hoops 10mm it is the perfect combo

Hi Payton!
So gorgeous 🌸✨! We love that the Solar Halo is giving you that perfect pop of color in your thirds—and paired with the Celestial Hoops and Blue Hour Titanium Hoops, that's such a stunning combo 🌿💎.

it's perfect
a little smaller than i hoped, but it's beautiful. i was in desperate need of new earrings due to being allergic to other metals. i'd been following cords club forever - should've made a purchase the first time i found them years ago! if itchy skin is your problem, cords club earrings and jewelry fixed that problem for me. they came in a very nice reusable orange branded case that can hold up to 3 pairs.

Hi Jessica!
So happy to hear this 🌸✨! Even if the size wasn’t exactly what you pictured, it’s wonderful that the earrings are giving you the comfort you’ve been searching for after struggling with allergies. Knowing they’ve solved the itchy skin problem and that you can enjoy them in that reusable orange case makes us so glad you finally joined Cords Club 🌿💌.

I’d love these in some more colors!
These are perfection and so comfy. I’ve been wearing them in my second earlobe piercing since the day I got them.
I’d love some more deep blue to match. Maybe a lightening bug with a blue gem bum for the ghost lightning bugs of WNC. A blue triangle like you have done with the black gem trio would be nice too.

Hi Lisa!
We're so thrilled to hear the Solar Halo Studs are absolute perfection and that they've been such a comfy everyday staple in your second lobe! 💖 Your ideas for more deep blue pieces sound absolutely dreamy—a lightning bug with a blue gem would be so magical, especially with that sweet WNC connection. 🌿 We love hearing creative suggestions like yours, and a blue triangle would definitely be stunning too! ✨

Cool piece
I had to get this piece from the Blue Skies drop. The sun with sapphire is so cool! It gives me book fantasy vibes. For anyone on the fence it's a great piece and not too big, plus it doesn't poke or catch on anything.
