If you want a chain that can go from work to the gym without coming off, start here. This O ring chain is 12mm wide. It's a chain of round rings, each joined to the next. It's made from 316L stainless steel. We cut it to the length you order in our UK workshop and finish it by hand.

It's non tarnish and water resistant, and 316L stainless steel is hypoallergenic for most users. It fastens with a lobster clasp, which we fit ourselves.

It comes in lengths from 16" (41cm) to 26" (66cm) in 2" steps, with an optional 4" (10cm) extender chain. Hold a tape measure round your neck where you'd like it to sit, and read off the length before you choose. It works with a T-shirt and under an open collar alike.
