DESCRIPTION

She's cute, she's versatile, she's out of the world! Similar to our original Lunar Phase Flat Back Stud, this version is quite a bit smaller and it features an opal, rather than a clear zirconia.

This listing is for a  single ASTM F136 implant grade titanium push-pin flat back stud.

Sold individually.
Measurements: Post measures at 1/4 inch (6mm) length, with a 4mm disc on back. 18 GA (1mm). Flower is approx. 6mm 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.

Colors available: 18K PVD Gold Plated Titanium, Titanium, Synthetic Opal

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 warm water with a few drops of dish soap for about 15 minutes. Gently clean with a soft cloth and store safely.

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:

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?

Both! Grab a single if you’re mixing and matching, or a pair to save 10%

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!

    Celestial Vibes for Days

    I bought these cuties in gold to wear with the opal micro studs. I love a good celestial vibe and opal with gold is an absolute dream. These studs are small, but legible from a distance what they are. The op catches the light in a stunning way. And the celestial vibes?!? On point. One of my stack pairing im most proud of and definitely my favorite gold set I’ve gotten.

    Hi Victoria!

    I'm absolutely thrilled to hear you're loving your Mini Opal Lunar Phase Flat Back Studs and that celestial vibe they're giving you! 💫 The combination of gold with opal is truly magical — there's something so dreamy about how those opals catch and reflect the light, especially when paired with that warm gold tone! It sounds like you've put together such a stunning stack pairing, and I'm so excited that this has become your favorite gold set! The fact that they're small but still so recognizable and eye-catching from a distance just shows how beautifully designed these lunar phase pieces are! 🌙
