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!

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.

These are great pens: precise without being scratchy. They are my go-to pen now when I am too impatient to use a fountain pen. The Mandarin Orange is a nice mark-up color.

This is a gorgeous color of orange. I prefer it far over the regular orange, which appears very neon. This Mandarin Orange has just enough red in the ink to make it a bit deeper and richer in color. I use the Uni-ball Signo UM-151 for taking notes, and this pen really does the trick.
