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!

Excellent pen for those who like a fine line, but not too fine. Has much more ink capacity than Uni-ball Signo pens available in your ordinary office supply shop. Similar tip though. The grip is useful but not cushiony.

The main difference for me between the Signo and the Hi-Tec C is the tip of the pen. The Hi-Tec has a needle point with some give to it, so if you are prone to writing hard, the Signo might be better. I have not had any ink flow problems with this pen (I had some issues with the Hi-Tec C due to keeping it in the wrong position in my pencil bag).

If you have a heavy hand and like less give on the pen tip, the Signo might be the best choice for you. I haven't really found a difference in ink quality between Signo and Hi-Tec C, but I haven't dumped any water on my writing for a while.
