This is for a Namco Negcon Sony PlayStation 1 controller.  This is the Japanese version, and this is in the original box and the controller is still wrapped/sealed in the original plastic.  Original cardboard box insert is here, as well as the original paperwork (see pictures).  Controller has never been used, and it's rare to find one of these in unused condition. Box shows minor edge wear and a few stress marks near the edges.  Minor wear to flap hinges.  Paperwork has some curling from years of storage in the box.
