Uni-ball Signo (DX) UM-151 Gel Ink Pen - 0.38 mm - Bordeaux Black

I LOVE this pen, and all the DX UM-151s. I teach at the U of Utah, and this is the pen I use to grade all of my student's papers. The tip is fine enough that I can make little corrections in the margins and between lines; the "Bordeaux Black" color is red enough to seem like it's chastising my students for their silly mistakes, but not so red that they feel violated (turns out that bright red pens have a negative effect on students); and the smoothness is unlike any other pen with a tip this fine. The "blotchiness" that another reviewer mentioned is, for me, more like a fountain pen's "flair" once you get more used to it (perfect for writing kanji). Finally, one of the greatest features about this gel pen compared to every other gel pen I've used is the speed at which it dries--it's a smooth, fine gel ink that won't smudge. Awesome, awesome pen. Also great for writing in the margins of books.

A terrific color that is truly versatile -- simultaneously professional and fun. I use for taking minutes, editing, as well as for spicing up a party invitation or note. A reliably designed pen that has yet to skip, bleed, or go on a lunch break!

So sad about this pen. I liked the flow of the ink, but after using it once, it leaked all over the place. Won't buy this model again.

This pen could be my new favorite. It's comfortable to hold and writes extremely smoothly, and the ink is a beautiful, unusual, but dignified burgundy color (I mean, bordeaux!). I just wish there were refills available!

I love these pens - but this is one of my favorite colors. Not quite black, not quite red - it's a good in between but still professional enough to use at work/school. It’s very comfortable to hold and didn’t strain my hand after extensive writing. I wish the grip was a little longer, and extended to the end of the barrel because I grip my pen quite low, but I can manage. A sturdy, well built nib that is still surprisingly smooth and not at all scratchy. The ink dries very quickly so very low risk of smearing! Overall, I am a big fan of the Uni-ball Signo DX line.
