Sheaffer 300 ball point hits that price, is what I have.
Pro’s – good weight, (actually, heavy, suppose that depends on you preference)
– nice writer
– refills last ages.
– spring action pocket clip so its not going to get bent.
– Good diameter, feels nice in the hand.
Con’s – metal barrel, mine’s been dropped a couple of times. Has a dent and a bit scratched, but I work in an industrial setting, might not be a problem in an office.
Nice pen link.
