DescriptionSpecificationsFrequently Asked Questions
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!

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!

I write incredibly small and the DX in Brown Black (0.38 and 0.28) is my signature pen. I've tried Hi Tec Cs (in 0.25, 0.3 and 0.4), Pentel Sliccis (in 0.25 and 0.3), and Zebra Sarasas (0.4). Each is a very different writing experience and each have their strengths. For every day writing, though, my heart belongs to Signo DX.

The tip is very strong; some say it's scratchy, but that makes me think of an unpleasant sensation. Instead, I'd say it definitely feels firm and precise (but not grating). Unlike Hi Tec Cs, they don't need to be "primed" by scribbling a bunch before the ink flows evenly. The brown-black ink is gorgeous; it's dark enough that it doesn't look gimmicky or childish (though I love those as well :D) but just brown enough that it looks subtly different and has a rich warmth to it.

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.
