DESCRIPTION
Meet the Cauldron Flat Back Stud! This little stud features an onyx-colored gem and three polished spheres that are set into a triangle shape at the top. The prongs are thicker than our other gemstone studs, giving the illusion that there's a base on the "cauldron".
None of these features were meant to come together to give us "cauldron", but honestly, looking at this piece there was really no other way to see it! Happy Spooky Season (though this versatile stud can work all-year round)!
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud.
Measurements: Post measures at 1/4 inch (6mm) length, with a 4mm disc on back. 18 GA (1mm). Black gem is 2mm. 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 plate (for gold color), black zirconia
Colors available: 18K PVD Gold Plated Titanium, Titanium
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.
*Please see site return policy for more information regarding flat back studs!

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!

- April S. S.Verified Buyer2 months agoRated 5 out of 5 starsPerfect Spooky Season Stud 🎃
I absolutely love the Cauldron Flat Black Stud! It’s exactly as described and looks even better in person. The design is simple but perfect for adding a subtle spooky touch, especially during the Halloween season. The flat black finish gives it a cool, slightly edgy vibe that pairs well with just about anything. Shipping was quick, and the whole experience was smooth from start to finish. Definitely a great little addition if you’re looking to bring some spooky season energy to your style!

CCCords Club4 months agoHi Emmeline!
We're so happy to hear you find the Cauldron Flat Back Stud absolutely adorable 💫! It's wonderful to know it fits nicely and comfortably—that's exactly what we love to hear ✨
✨ Jace with Cords Club - Sam L.Verified Buyer8 months agoRated 5 out of 5 starsPerfect addition to the earring stack!
This earring is so adorable and the perfect thing to add to an earring stack! It's small enough to not overshadow any of the more designed studs but still large enough to add a nice flair. The gold and black is a super classy combination and this one is a great staple, especially for helix piercings!
CCCords Club8 months agoHi Sam! 😊 Love how you’ve described the balance — subtle yet striking, and totally stack-enhancing! Gold and black is such a timeless combo, especially for that helix pop ✨
