DESCRIPTION
Our Zirconia Constellation Flat Back Stud is micro in size, allowing it to fit in a lot of different locations! Even better, with its sleek bezel setting, this tiny gem is unlikely to snag on clothing.
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud. Note the sizing below, as this micro stud is tiny enough to get pulled into a larger-gauge or stretched out piercing hole.
Measurements: Post measures at 1/4 inch (6mm) length, with a 4mm disc on the back. 18 GA (1mm). Front is approx. 2mm in diameter. Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurement before ordering.
Materials: ASTM F136 titanium, 18k PVD gold plated ASTM F136 Titanium (for gold color)
Care: These are tarnish-proof and waterproof. With all items of this material, if you come into contact with chlorine or salt water, cream, lotion, perfumes, etc. Rinse in water and dry if this does happen. When not wearing, store in a dry, cool place.
CARE
Soak your studs in a bowl filled with warm water and a few drops of dish soap for about 15 minutes.

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!

- Payton J.Verified Buyer49 minutes agoRated 5 out of 5 starsPerfect for Small Areas
I have one of these in my tragus and another in my forward helix and they are the perfect size for some glimmer in those areas. I forget they are there sometimes because they are easy to sleep in and I still wear airpods with the one in my tragus and I can't feel it. There is also something about the setting of the gem that is so cute in my opinion.
CCCords Club25 seconds agoHi Payton!
So perfect 🌸✨! the ideal size for your tragus and forward helix—giving you that perfect glimmer in those smaller areas 🌿💎. And the fact that they're comfy enough to sleep in and totally unnoticeable even with your airpods in? That's exactly what we're going for. Plus, we're so glad the setting of the gem is catching your eye the way it does!
