From a newbie - I moved up from a few cheap fountain pens to a
Waterman Phileas with a medium nib, which is terrific. I used one
cartridge, and then used the converter. I filled it with black Quink I
bought from Staples and am very satisfied with the results. While I'm
not looking to change inks, I was wondering if there are thoughts on
other good black inks for this pen, i.e., is Waterman ink better and
worth a separate purchase? How about other brands? Thanks
