ASTM F136 Implant-Grade Titanium Flat Back Stud with Cubic Zirconia Solitaire, 3 mm / 4 mm / 5 mm / 6 mm, 18G Internally Threaded
A Classic CZ Solitaire in Implant-Grade Titanium
Crafted from ASTM F136 implant-grade titanium and set with a precision-cut cubic zirconia, this flat back stud combines timeless simplicity with everyday comfort. Like every EaseTi piece, it is built on implant-grade titanium: nickel-free, lightweight, biocompatible and made for sensitive ears.
Titanium Silver or 18K Gold PVD
Choose natural titanium silver, which is unplated and polished, or a gold-tone 18K PVD finish over titanium. Both versions share the same ASTM F136 titanium base.
Four Stone Sizes, Comfortable Flat Back
Choose a 3 mm, 4 mm, 5 mm or 6 mm stone and a 6 mm or 8 mm post. This CZ solitaire flat back stud lies comfortably against the ear. The 18G (1.0 mm) internally threaded post (M0.9 thread) keeps the top securely in place, and the threading stays out of contact with your skin.

Ordered 3mm for my conch. It’s tiny tiny. Like if you want subtle this is it. If you want bling go bigger. Wish I went 4mm but that’s on me not on them.

Didn’t expect the metal to feel this nice.
Barbara Cooper –
Takes forever to screw in honestly. My fingers are too fat and I dropped the back like five times trying to get it on. Almost gave up and returned them. But once it’s on it’s not going anywhere. So idk. 4 stars I guess.

I bought these specifically because they’re ASTM F136 titanium. I did my research okay. My piercer said that’s the good stuff and honestly my ears agree.
