SPS4F - Black Ink Fine Point Fisher Pressurized Refills For 1950's Paper Mate Pens

This refill exhibits the same quality as the other Fisher refills and fits and functions in the BIC Clic and Skilcraft-U.S.Government pens. I add a small spacer at the end of the refill when I used it in the Clic because I wanted the tip to extend a little bit more than it did otherwise.
