This is a very old item, production of which has been discontinued. There are some stains and rust on the metal parts, but it is well-made and can still be used. My aunt has enjoyed knitting as a hobby for many years, but she has become elderly and is letting go of her cherished tools. I hope that someone will continue to use them for their handicraft life.
