Paper Mate gained a reputation, in the 1960s, for high quality ballpoint pens. This was based, in some part, on the writing characteristics of the 'lubriglide' ink cartridge.
This pen came to me as part of a number of pens from a stationary shop that closed down many years ago. It is in new condition with the original box and guarantee.
As expected, the original refill had dried so I replaced it with a new Paper Mate compatible refill. I chose red for the ink colour, partly because the pen is red but also because the pen may be useful as a highlighter in note taking.
I can't be certain about the age of the pen but I have seen a Paper Mate advert from 1963 featuring this exact pen.
