Find Your Fit

Flat-back earrings are measured from the end of the post to the back of the frontal. Our selection includes four sizes—5mm, 6.5mm, 8mm, and 10mm—ensuring a proper fit for everyone.

What’s My Size? 4 Ways to Measure

  1. Insert an earring into your piercing and subtract the protruding length from the total post length.
  2. Lay an earring flat on a millimeter ruler to measure.
  3. Refer to our Sizing Guide for average piercing sizes and more information.
  4. Visit a tattoo or piercing shop and ask to be measured.

Flat Back Earrings

Flat back earrings are a modern twist on traditional designs, offering comfort and security, especially for cartilage and advanced piercings.

Care Tips:

  • Choose the Right Length: If your earring won’t screw in all the way, it’s likely you have the incorrect post size. The right post length is crucial to avoid losing your jewelry or irritating your skin. For most healed piercings, a 6mm or 8mm post is comfortable. However, thicker ears may require a 10mm post, while thinner ears may need a shorter 5mm post. 
  • Secure the Fit: Regularly check the screw of your flat back earrings, especially after swimming or wearing tight-fitting hats, to ensure they are still tightly secured.
  • Gentle Cleaning: Use a soft toothbrush and mild soap to clean your earrings once a month. Avoid ultrasonic or harsh chemical cleaners, which can damage stones or metals.
  • Avoid Harsh Products: Keep face wash, lotion, sunscreen, and shampoo away from your earrings. The chemicals can dull the metals and affect the gemstones.
  • Rinse After Showers: After showering, rinse the piercing area with clean water to remove any residue.
  • Pat Dry: Gently pat the earrings and surrounding skin dry with a clean paper towel. Avoid fabric towels, which can harbor bacteria or snag the jewelry.

Fantastic!

I bought these Ruby studs to live in my 3rd lobe piercing until I feel they�re healed enough to switch to hoops. These are fantastic. The stone is a vibrant red with good presence. I like that the posts are push in and also threaded. It makes it easier to put them in and the threads make them secure. I haven�t taken them off since I got them. They shipped almost immediately (then it took USPS 10 days to bring them 20 miles, but that�s USPS, not this seller). I will be buying more studs from this seller.
