If you've ever bought a chain that looked nothing like its photo, here's exactly what this one is. This round box chain is 2mm wide. Each link is a small box, joined end to end, so the chain has clean, straight lines. 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. Before you choose, wrap a piece of string round your neck where you'd like the chain to sit, then measure the string. It looks just as right on its own as it does with another chain.
