This is the protective leather pouch that would have come with your 1990-1991 Corvette ZR-1 Owner's Manual kit (inside the "pizza box"). It measures 12 x 15 inches (30 x 37 cm). It is new old stock and has never been used. It may have some very minor scuffs from being taken in and out of the box over the years. This is the pouch only, with nothing inside.
