Marquise 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!

So cute & Exactly what I needed!
Let me start by saying that I love these earrings! I so badly needed flag backs in my second and third gold cause normal earrings were so uncomfortable and they messed with my ears. The only thing I will say is getting them in is quite difficult. The posts are maybe just a sliver too short and the back of the earring is what needs to go into your ear. My third hole is a normal gauge piercing but I still had difficulty getting them in and it barely stuck out enough to get the front to line up. I had to get assistance due to the angle but that’s not their fault haha overall, very happy and glad I got them in. They are nice and snug. I didn’t have to bend them anymore than they came.

Hi Jordan!

Thank you so much for this detailed review! 😊 We're thrilled you love the Marquise Flat Back Studs and that they're giving you the comfort you needed for your second and third holes 💕✨ We totally understand the initial challenge with getting them positioned—the angle can definitely be tricky at first, but you nailed it! So happy to hear they're fitting nice and snug now and that you're loving how they feel 🌸. Enjoy styling it, and thanks again for sharing your kind words! 😊

😘~ Elvie with Cords Club
