Built from 316L surgical-grade stainless steel, our 3mm Round Box Chain is durable, comfortable, and made for daily wear. Every chain is carefully hand assembled in our USA-based workshop, where each link and clasp component is fitted and secured for a reliable, all-day fit. It won’t tarnish. It won’t fade. It won’t react with your skin. From the smooth, rounded box links to the polished cross tag, every detail is designed to balance strength, comfort, and lasting quality.
