Uni-ball Signo UM-151 gel ink pens, also known as Signo DX, are known for their smooth writing and exceptional ink quality. And, to everyone's delight, there is a sea of colors and tip sizes to choose from. Find the perfect pen for any task, whether it's writing meticulous notes, marking your calendar, or decorating your scrapbook with colorful captions.

Everything about this pen, from its solid construction to its carefully-formulated ink, ensures a wonderful writing experience. The sturdy tip does not bend or break, even with heavy-handed use. The pigment-based ink flows smoothly and is waterproof, fade-resistant, and feather-resistant. Much of that is due to special viscous properties of the ink. The ink is viscous while in the barrel, but as it passes through the pen tip during writing, the viscosity drops. This results in smooth ink flow. Immediately after it hits the paper, the ink returns to its viscous state, which prevents feathering. You are left with beautiful clean lines that you can enjoy for a long time!

My absolute favorite gel pen and gel pen color for every day writing. I can't go back to plain old black. Too bad there are no refills for this pen barrel in 0.28. Boo! I will never use any other brand other than Uni for gel pens. They write like a dream and 0.28 is the perfect fine line for me.

The color is exactly as I imagined! I really love how it's a dark color but not too dark, so it really does have that deep brown color. I planned on using this in my planners and small notebooks, so I wanted a finer tip. I could see this being good for my drawings as well. Very content with the product!

(Disclaimer: I use cheap paper, which might make a difference, I suppose.) Certainly my favorite pen. The UM-151 line in general is consistent, requires basically no pressure (compared to pens in the G-2 line, for example), and while I've found the regular black ink to sort of expand once it hits the paper, resulting in a thicker line, the brown-black lays down the line it should (for reference, the G-2 05 and the DX/UM-151 .38 seem to have close to same line thickness in regular black; same with the G-2 .38 and UM-151 .28). If you tried this tip size in black and it was thicker than you wanted, I'd suggest giving brown-black a shot. Some have noted the pen's "scratchiness" because of its fine point, but I personally don't think it's bad enough to be considered a problem; it just isn't as free-flowing as a bolder pen. The downside is that it's essentially nonrefillable in anything but black. Also, the description says it will take a .38 refill; the description sits on a throne of lies. Just so you know.

The Uni-ball Signo U-151 at 0.28mm with Brown/Black ink is my favorite pen, size, and color. I write with these and I like how the brown/black ink looks on notebook paper. I have accumulated a large pile of drained pens.
