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!

Emerald Green is such...

Emerald Green is such a wonderful color. At first, when I was trying to decide whether I should get it or not, I was in doubt because of how light the color appeared in the display picture. But when I got it today, it's much richer and darker. It's more of a .. eccentric green.

I love signo and they didn't fail me on this one, the color is sooo pretty and I am not one for colors, but this is an exception :) I would suggest to get smooth paper to write on, on cheap paper it rips through unless you write softly-I do not-but other than that it is a wonderful pen!

This is a great pen. It writes very smoothly, and works well for both writing and drawing. It has a good strong coloured ink as well. I think one of the advantages of this pen is that you can make faster pen strokes without it skipping. It also has a good weight to it.

I think I might have to agree with those that prefer the Signo DX and the Pentel Slicci over the Hi Tec C, now that I have tried all of them. The Hi Tec C is still a good pen, and comes in the widest colour selection. However I think of the DX and the Slicci I will enjoy writing with and using a lot more.

I've never tried these pens before and I'm always a bit suspicious of gel pens, but I'm very happy I made the purchase! The emerald is a very beautiful shade of green that borders on teal.
