DescriptionSpecifications
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!

The pure pink color is a pink with a touch of blue so it looks like a pink with a tinge of purple, noticeably different from pink (fluorescent w/ touch of orange). Baby pink is more of a bright strong pink, not at all pale or light.

The pen itself I love. For writing quickly and smoothly for an extended time period, I prefer the .38. The .28 is good for smaller writing and is actually preferred for margin writing on coated textbook paper or underlining texts.

I prefer Signo UM-151 pen for continuos writing due to the comfort grip and sturdier conical tip when I apply more pressure compared to .4 Hi-tec-C pen. H-tec-C 's with grip are better for smaller yet clear and precise writing when calm. I also keep the non-grip .4 hi-tec-c pens in my stash for the unique colors that aren't available in the signo.

First, I am a paper freak. Second, I am a pen freak. When the New York Times featured an article about these Uni-Ball Signo pens, I just had to have them, even though I have more than three dozen pens from various doctors' offices, press events, giveaways, etc. Because of the write-up, I never expected Jet Pens to have them in stock...but lo and behold, they did!!! And I do love these pens.They've evenly and smoothly glided over every textured paper I have tested them on, they're comfy in hand, and if you have nice handwriting as I do, they can serve a multitude of handwriting needs. Go for them. They're terrific and so is Jet Pens. ( I ordered many different colors.)

Comparing to baby pink, it's color is darker & chic.

I found 0.38 mm is the most comfortable & precise pen tip. Pure pink ink does not smear, & it dries very quickly. (Green Black, Red & Orange ink smears badly...) This "pure pink" ink stands out beautifully when it is combined with Signo Blue Black & Light Blue. I don't like using Red & Black ink on white paper, since its contrast hurts my eyes : (
