This is a spool for a Saltist 150, with a diameter of 36mm. I was using it with a 16HRF PE Special. I am selling this because I am organizing my tackle, and I am also selling the same reel. If you purchase them together, I am considering a small discount, so please feel free to inquire. There are some scratches on the line winding parts from use, but there are no major scratches or damage, and I think it is in good condition. Please feel free to ask any questions.
