I got this very thin square stainless wire, and played with it a bit. It's fun, light, easy to wear, but it isn't as strong as I'd like. It's still strong, and you can wear it around town, but I wouldn't choose it for climbing trees or hiking.
We're finally getting our stainless steel cuffs online! These are the toughest things we make- anything that you can do that might mark or hurt these, well... the cuff will be the least of your worries. They aren't as flexible as our copper cuffs, but the form is still pretty forgiving, so the same size chart works.
Sizing is quite flexible, but there's nothing that fits everyone. We've made sizes for everyone along the gender spectrum.
X-small- best fit on a wrist 5.5 around. Will comfortably fit wrists 5-6 inches around. This really is very small. Small- best fit on wrist 6 inches around. Will comfortably fit a wrist 5.5-6.5 inches around. Medium- best fit on a 6.5 inch wrist. Will comfortably fit a wrist 6-7 inches. Large- best fit on a 7 inch wrist.
