I picked up a 4-pack of these at Staples a few years ago and really loved them
for work - I'm an architect and often have to annotate drawings in different
colors for others to correct and coordinate. Then they started running dry and
I have been able to find them anywhere, until now. However, I think when I
place my order, I might be giving the similar looking Bl@ck Worker a try, since
it comes in a finer .3mm tip. Thanks JetPens!
