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

I want to disagree with the reviewer that says this color is not dark enough to use for business. I use this pen anywhere I would use a black, or blue-black pen and am quite happy with it. It is especially nice to use if there are several people writing on the same papers, and you can identify your own writing by color. It is not quite as distinctive as blue-black in my opinion, but just subtle enough that few people will notice it unless they know to look for it.

Also, I'd like to say that I find the 0.28 and 0.38 pens last much longer than the 0.5 size pens. It's quite noticeable to me. I prefer the 0.38 size overall. The 0.28 can be hard to read for some people depending on the lights or their eyesight, and I avoid the 0.5 just because it runs the ink out too fast.

Great pen!

Main complaint is that the brown is not dark enough to use on professional documents. I was hoping it would be really dark, and it is more of a solid brown.

Pen is as sturdy as the blurb says. Good choice if you like having a lot of pen in your hand. Also comes in a few colors that Slicci doesn't, at least. This one is my favorite, really solid color. Looks a bit like black coffee. I really like coffee.
