Is the Pelikano Roller... An actual roller, or a fibre tip pen? I can't tell.
Says "cartridges for rollerballs" on box box, but closeups seem like it's a fibre tip pen, much a la Parker 5th
Is it possible to hack the cartridges somehow, to replace the Royal Blue in it with something more interesting, such as Iron Gall inks?
What is the general consensus regarding this rollerball?
