It's a bluish-silver, satin-like material. I've only worn them twice, about 10 years ago, to a friend's wedding, so there's hardly any dirt. The size is listed as L, but they're not very big. They feel a little big on me, and I usually wear a 23.5cm. I don't know the manufacturer. There's no box, so I'll send them in a different shoe box. Color...
