Cauldron 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!

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.

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

Perfect 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!
