Product Story＋

Dimension born of the spiral — simple, yet quietly eye-catching.

The appeal of a rope chain lies in its distinctive dimension. Finely twisted links catch the light from many angles, creating a depth of shine that flat chains cannot achieve.

The 2mm is delicate and understated — an excellent base for layering. The 3mm carries a leading presence on its own; just a glimpse at the collar of a tee sharpens the whole outfit.

Lengths run from 45cm to 60cm — from a 45cm that sits at the collarbone to a 60cm that falls to the chest, choose the length that suits your styling and taste.

Because it is 316L surgical steel, wear it every day without worrying about summer sweat or the sea. Each rope chain, carefully finished one by one, adds a refined accent to your everyday.

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.
