## 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!

## Features

- Users can enjoy clean and even flowing lines, and the strong tips can withstand all the heavy handed writing you can offer.
- Like all our other pens, the Uni Signo DX is highly sought after by artists and writers alike, but difficult to find in the US.
- Includes 2 pieces of 0.38 Gel Ink Pen.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    It writes so smoothly that it's a pleasure to write
  

*by G***S on Reviewed in the United States on August 24, 2020*

Gee, is this pen nice!  I just fished it out of all the pens in my desk drawer.  As I was writing, I thought, "What pen is this?  It must be part of one of my sets of gel pens."When I looked up "Signo" in my orders, I realized, "Oh, this is that expensive single pen I ordered".I'm going to order another one.

### ⭐ 







  
  
    These stink.
  

*by S***. on Reviewed in the United States on January 19, 2021*

They're great right up until they're not. Within a week both of them stopped writing, and I don't leave them uncapped or anything. Waste of money.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Fine Point Pen
  

*by L***A on Reviewed in the United States on April 28, 2021*

I love how these pens write.  I like the shade of blue and have also had other colors, which are equally nice.  The ink does not bleed or smudge.
