I specifically bought the Parker Vector because I read on this forum that it was a wet writer and excellent for iron gall inks. I can confirm this is true. I'm very pleased with this little writer. A good, sturdy, inexpensive pen.
The Parker Vector nibs are interchangeable with an old Parker Calligraphy Pen set I bought years ago. They look identical, in fact. I have left an ink cartridge in one for years, and despite my neglect, it still wrote fine when I picked it up.
A small-volume ink converter-- my only complaint with this pen. If something were to happen with this pen, I would definitely replace it with the same. I couldn't be happier with how well it handles iron gall ink, or quink cartridges for that matter.
