DescriptionSpecifications
Uni-ball Signo gel ink pens 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 ink flow of this pen is amazing! it's so easy to write with. the only thing is that i was expecting this to be more of a vibrant orangey-red. instead it looks to me like a duller orange color. on the plus side, the .38's do show up really well.

The Uni-ball is a good pen, but the Frixion is my go-to pen.

Uni-ball is a great brand and the make many great pens but this in my opinion was a down fall. The .38mm tip is scratchy, and so sharp that it tore my paper. The ink is too viscous for this small of a tip and often skips. Maybe I would try these again in a larger tip size. Try them for yourselves though, maybe in a larger size and you will like them. They are comfortable to write with, speaking in terms of grip and body size.
