The Uniball Signo DX, a Japanese gel ink pen in .28, .38, and .5, writes smoothly to create bold colorful strokes. This pen also happens to be my absolute favorite Japanese gel pen. I have been using the bordeaux-black and brown-black regularly since 2000. I find the tips to be stronger than most gel pens, which is important to 'heavy-writers' like myself.
