Pilot G-2 Gel Ink Pen Refill - 0.38 mm - Black

While the price is questionable, this 0.38mm ink is truly a pleasure to write with. Unlike some ultra fine ball points, the G2 0.38mm ink writes smoothly and does not feel like it's scratching the paper. The lines, however, are the same thickness as a 0.5mm ball point pen because the gel ink bleeds into the paper, albeit very slightly.

As far as price is concerned... well, let's just say I was able to pick up a pack of 2 0.38mm pens at a local Wal-Mart for about $2.60 pre-tax. Your mileage may vary.

Just buy a new pen for 5 cents more.
