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!

Awesome awesome awesome!...

Awesome awesome awesome! I bought these because of the fine tip, and was concerned about spending a lot of money on refills (reviews have said that the ink runs out really fast). It does run out, but I have gotten through an entire semester on two ink cartridges (and I take a LOT of notes). This is my go-to pen.

I thought that this 0.28 tip was a little bit scratchy. I ordered both the 0.28 and 0.38, and I have to say that I like the 0.38 better.

The ink flow is very consistent and the pen tip is just like a normal pen, unlike the slicci which has a fairly sturdy tip and the hi tec c which has a unconventional tip that looks nice and doesn't break unless you write extremely hard.

I would say that this is a good pen for people who want to write small, and is definitely better than the hi tec c 0.25 tip, which is tedious to write with.

Either way, I probably won't buy this again, due to the scratchiness, but it IS a nice pen and is recommended for people who like very thin lines and dont mind the slight scratchiness as much.

It pains me to give this pen a 4 star rating. It deserved the full 5 stars, that is when it wrote. When I first bought it it wrote wonderfully, the tip was super small, great for taking notes, the ink was vibrant and smooth. Ive had these for about three and a half weeks, and they just stopped working. The ink barely flows anymore, and the worst part is that there is half the ink left inside. Great...when it actually worked

SUPER GREAT PEN!!! Insanely small, thin and clean lines. The color is super crisp and vibrant. Virtually my ideal go to pen for notes and scribbles. However there is one problem that distances it from being my number one pens list. That horrible and atrocious reaso being that I cat give this pen 6 stars ;)
