Lightning Bolt Flat Back Stud

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

Learning curve
These are great for people who love to not take their earrings out everyday. There is a learning curve to get them in and should check them daily to make sure they don’t loosen but besides that I’ve been getting compliments regularly on them

Hi Karyl!
We're so happy to hear the Lightning Bolt Flat Back Studs are hitting the mark with both style and comfort! That combination of super cute and sleep-friendly is exactly what we love about flat backs—they're designed to be gentle enough for all-day (and all-night) wear without any irritation. The lightning bolt design adds just the right amount of edgy charm while staying perfectly comfortable. Thanks for the wonderful review!

A great gap filler
I use this little lightning bolt for one of my standalone piercings. It's never fallen out or gotten loose, and I'll wear it for weeks at a time.

Hi Liz!

The Lightning Bolt Flat Back Stud is such a perfect little accent piece—we love that it's become your go-to for that standalone piercing! ✨ It's so great to hear it stays secure and comfortable enough for weeks of wear without any issues. There's something so satisfying about finding that perfect "gap filler" that just works flawlessly! 💖 Thanks for the awesome 5-star review!
