## Overview

Sold as a set of two black pens, it’s a highly sought-after tool favored by professionals and artists for its reliability and refined performance.

## Description

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!

Review: Very good overall - This is a very good pen, but it isn't my first choice since I've got several gel pens with 0.3 or smaller tips to choose from. The Signo DX 0.38 writes smoothly, and glides with only the slightest hint of scratchiness over the paper, though not enough to be problematic. The line is consistent and there aren't any significant problems with skipping, jus a tiny amount of starting fade (it still writes, but doesn't reach full density until after a few strokes). The body is solid and comfortable, and it has a nice rubber grip. The cap posts with a snap instead of a friction fit, which is always nice to see. The point is a robust cone instead of a more fragile looking needle point. I usually list pros and cons in my reviews, but this pen's only con is really a personal preference - I like even finer lines than this one has. If the line width meets your preference, this pen is an excellent choice, and while others might equal it, I doubt any would surpass it by any great degree. I really need to try the Signo DX 0.28.
Review: Thumbs Up! - I'm an unofficial collector of pens and always looking for 'the perfect' pen. When I use a pen, I look for one that maintains a steady flow of ink, writes consistently on surfaces, has a finer point, feels comfortable in the hand, and a professional appearance. I have been using the Uni-ball Signo for just over a week and it has become my 'go to pen.' The flow of ink is consistent though on writing surfaces that have a sheen type of coating, I notice the width of the ink line extends a little bit fuller -- almost like a fountain pen. I like the quality of ink as it is a solid and rich color (black). The tip of the pen is very sturdy and does not flex. I am enjoying the pen and even ordered the pack with multi colors which I will be using to color code my calendar and task list.

### ⭐⭐⭐⭐⭐ BEST PENS IN THE WORLD
*by D***V on June 23, 2017*

BEST PENS IN THE WORLD. I will never write with anything else. I am not even a pen fanatic. I always thought a pen was just a pen. My husband actually got for these for himself and gave me one to try, and I ended up using all mine and stole his (He doesn't write as much as I do). Ordered more and the colored set, which also is fantastic. Smooth ink flow, not too heavy, can write on fine paper without bleed through and can write teeny tiny in the margins of books and you are still able to read it clearly without any bleeding or smudging. I can not say enough good things about these pens. They have made me a believer in quality writing instruments.
