Hope you don’t mind looking a bit dangerous, the Raven Tungsten Ring is not exactly subtle in disguising sinister intentions. A closer look, but not too close: black ceramic base with a polished tungsten carbide centre. That’s good enough, back away slowly now.
8mm wide, 9.4 grams weight and numerous questions remaining that the Raven refuses to answer. Where did it come from? What nefarious deeds has it planned? It’s best just to do as it says and not put up too much of a fuss, you can try to talk your way out of trouble later.
