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!

As an amateur writer, I like to edit my work by hand. I type out my stories, then print them and mark ‘em up with good ol’ pens. After much trial and error, these Unis are my favorite by far. I have tiny handwriting, and the pen really gets in the trenches between the fine 12-point font size.

My main color to correct my docs is Bordeaux Black (a fantastic option to the dreadful red), but I want to switch up the colors in this line. The purple is a very vibrant and strong color, and immediately reminds me of Marie from Breaking Bad.
I found that this specific pen skipped a little sometimes, which didn't really happen with the other colors I have. Not sure if it's the pen or the color itself, but I thought I'd point that out.

I am very picky when it comes to violet/purple ink. This is one of my favorite! The ink in this pen is the perfect balance of red and blue creating a violet that actually matches the cap.

The pen writes very well and dark enough for everyday. Thick enough for my small hands to be comfortable writing all day.
I would choose this purple over the pilot G-2 milky-purple any day.
