I love it when people have pen prejudice. ^_^ I prefer pens that bleed a bit, like a Sharpie extra fine or a Uniball vision micro. I loved my Waterman fountain pen, but I haven't found any ink cartridges for it in years and using as an honest-to-god fountain pen is annoying.

But my goodness, 0.38 is microscopic. Those would be amazing for drawing. I'm drooling over the tiny cross-hatching you could achieve.
