The largest dressmaking scissors / shears ever made by anyone, 16.5" long, manufactured by J Wiss & Sons in Newark USA.
Although they are a very rare antique, they are in perfect condition and they will cut fine tissue paper.
Very few were made because most people didn't need scissors this big so the 16.5" version is incredibly rare, I can't find another pair this size for sale anywhere. grab yourself a fascinating talking point and a rare Antique in one.
