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!

This is the Blue pen. The close-up tip photo features the Black pen.

As much as I love retractable clicker pens so I don't have to worry about losing the cap, the Signo UM-151 in 0.5 is the smoothest, most reliable, and most visually pleasing ink and body amongst all the pens I've used (Zebra Sarasa 0.3, Hi Tec C 0.4, Signo 207 0.5 & 0.38, Jetstream 0.7 & 0.5, Uni Style Fit 0.38).
This blue is bright (unlike Sarasa's blue which is oddly closer to navy or blue-black) without looking silly. I look forward to using this pen for many years to come and just continuing with refills.

I like the larger size barrel compared to the Hi-Tec-C and Slicci pens. The rubber grip is nice, and it runs a clean line. I found that the ink is waterproof as advertised.
