The Aslan Leather Jaguar cuffs are sturdy leather cuffs. These are made with good quality control in mind and a lifetime product guarantee to ensure your Aslan product stay nice. They are meant to fit a majority of wrist sizes, but those with small or large wrist might have issues with the sizing of the cuffs. The issue I had was that they didn't come with a G clip, so I can attach them to my Spreader Bar.
