Kite flying string - looks super strong! Kobacchi brand.

This is kite string, typically used for flying kites, but it's versatile and can be used for various purposes. I haven't had a use for it in decades, so I'd like someone else to have it. It's unused, but it was originally in a bag that had deteriorated and torn. After disposing of the damaged bag, it has been stored for many years. As a result, there is some dirt on a portion of the string, as shown in the first image.

Thank you for looking.
