A square design composed of straight lines and sharp edges. Among many rings with curves, its sharp form brings a sense of neat tension to your hand. Minimalist yet distinctly individual.

The material is 316L surgical stainless steel, excellent in durability and corrosion resistance. It is resistant to fading and discoloration, and is a skin-friendly metal also used in medical instruments. There's no need to take it off in the sea or bath.

Wear it alone for a clean look, or layer it with other rings to accent your own style. It's an everyday staple ring that will last a long time.

Customer Testimonials

★★★★
It's noticeable but understated. It doesn't tarnish at all, even when worn every day, and the best part is I don't have to take it off while working out.

I have a metal allergy, but since this is surgical stainless steel, there's no rash. I even wear it in the ocean and there's no discoloration, it's the best.
