Materials
ASTM F-67: Pure, unalloyed titanium. This is the safest metal for sensitive ears because it is the least likely to cause a reaction. We use this for almost all of our earrings.
ASTM F-136: Implant grade titanium. This is an biocompatible alloy containing aluminum, vanadium, and titanium. We use this for our flat back studs.
STAINLESS STEEL: We use this as a base metal for our bracelets and necklaces. We always use nickel free and lead free stainless steel. It is then plated with titanium nitride, a biocompatible material, to further protect sensitive skin.
COATING: Titanium nitride PVD is applied to our gold jewelry to give it an 18k gold color. Titanium nitride is a hypoallergenic material that is more durable and resistant to wear than gold plating.
CARE: Since the materials we use are non-tarnishing, our jewelry can be worn in the water and will not change color, rust, tarnish or turn green.
Tested for Purity
We lab test our earrings to ensure they meet our Clean Jewelry standards

Customer Reviews
I received two of these as a pair for Christmas. This was my first time putting in screw/flat back earrings, and the nano size made it very challenging. Once I sat down close to a mirror, I was able to screw them in securely. It's February and I haven't had any issues yet. I check them to make sure they are screwed on tight, and I've only had to tighten them once since putting them in in December. I love that I can put them in and go on with life. These are perfect for third or higher piercings as the flat backs are very comfortable to wear while sleeping. All of my TIni Lux earrings have been very healing for my allergic reactive ears.
