Sleep-Friendly
Hypoallergenic
Waterproof
DESCRIPTION
One of our most popular designs, now in larger size! A classic prong-set clear gem, this 4mm solitaire is the perfect flat back stud! It's great in a first piercing, but can still work elsewhere, like seconds or a shen men, depending on your anatomy.
This listing is for a single ASTM F136 implant grade titanium push-pin flat back stud. Note that the edges of the front piece can be a little sharp, due to the intricate detailing around the edges.
Measurements:
- 18 GA (1mm)
- Post is 1/4 inch (6mm) in length, with a 4mm disc on back.
- Approx. size of front piece is 4mm.
- Refer to listing images to get an idea of the size of the stud on-ear. Check your own ear measurement before ordering
Materials: 18K PVD Gold Plated, ASTM-F136 Titanium, ASTM-F136 Titanium, zirconia
Care: Water and tarnish proof with proper care. If exposed to salt water, chlorine, or lotions/perfumes, rinse off with cool-warm water and gently dry. When not wearing, store in a dry, cool place. Do not pull, twist, or tug on your jewelry.

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:
- 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?
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!

Great basics for everyday!
CCCords Club3 weeks agoHi Ashley!
We're so glad the Solitaire 4mm Flat Back Stud is working perfectly as an everyday basic for you!✨
—Jace with Cords Club 🌸✨ - Elaine F.Verified Buyer1 month agoRated 5 out of 5 starsFINALLY!!
I've given up a few times on wearing earrings over the years because every time I wear them, my ears get irritated and swollen. I decided to give these a try to see if wearing 24/7 might give my ears time to get used to them. That plus the titanium being hypoallergenic seems to have done the trick! I've had these on for almost 2 weeks and NO irritation. I'm so happy to be able to buy cute earrings!!
CCCords Club1 month agoHi Elaine!
So glad these earrings finally gave you the comfort you’ve been looking for 🌸 Hearing that you’ve had no irritation after almost two weeks of wearing them 24/7 is such a win—cute style and hypoallergenic titanium truly make the perfect combo 💌✨
—🌿 Jace with Cords Club - Pauline L.Verified Buyer1 month agoRated 5 out of 5 starsPerfect pairing
My go to for every day wear. I pair it with other studs.
CCCords Club1 month agoHi Pauline 🌸,
Love that the Solitaire 4mm Flat Back Stud is your go-to for everyday wear! That versatility is exactly what we're going for, and we're so glad it pairs perfectly with your other studs 💛 The fact that it's become such a staple in your rotation means everything to us ✨
🧡🌼 Jace with Cords Club - Lacey S.Verified Buyer1 month agoRated 4 out of 5 starsPull Out your Rulers
I thought they were going to be way bigger due to the first picture, circling which one it was. That must be a literal child's ear they are displaying because it's actually closer to the How to Wear picture. The front posts are also very slim, so I think it will wear out quickly over time which will make them useless if it breaks. They still are nice-looking and a small, everyday-wear simple earring. They are also exceptionally lightweight, which I enjoy.
CCCords Club1 month agoHi Lacey,
Thank you so much for your review of the Solitaire 4mm Flat Back Stud! We're glad you're enjoying them as an everyday-wear piece and that you love how lightweight they are.
Every ear anatomy is different, and we totally hear you on the sizing! We really appreciate you taking the time to share your thoughts about what you were anticipating versus what arrived. Your note about the slim posts is also super useful for us to know.
Thanks for letting us know your experience with these studs!
