Spirocore Medium Double Bass Strings, Set of 4

This is a Spirocore medium tension string.
I purchased it used several years ago and used it on an upright bass.
It has been well-used, so it doesn't have much sustain. It might be good for those who don't prefer the sound of a new string.
I'm listing it at a low price in case anyone is interested.
Please judge the condition from the photos.
