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!

Beautiful color and performance. The Signo DXs have a much smoother write in my experience than Hi-Tec-C's (in contrast to the reviewer before me), with rare blips in ink flow. I plan to try this color in the 0.38 mm size too.

Well, for me this pen is definitely *not* better than the Hi-Tec-C. The ink seems a bit watery somehow, or perhaps I'm influenced by the unexpected color. For "emerald" I thought it'd be a bit darker.... It writes fairly smoothly, but I actually prefer the Hi-Tec-C's grip and nib.

This has a fine clear line for writing in small spaces. I couldn't do without it.
