HNG-22 hinges are brass plated steel, gold in color, and these are new old stock, which means they came out of a factory that was using these back in the mid-1900s.  Well made, the sort of hinge you’d see on small boxes, brief cases, suitcases, tackle boxes, artist’s boxes, humidors, etc.  2 hinges per pack for $6 flat, USA shipping included.
