## Overview

The Uni-ball Signo DX UM-151 is a premium gel ink pen featuring an ultra-fine 0.38mm tip, reinforced barrel and tip for enhanced durability, and a smooth, smear-resistant hybrid ink. Favored by artists and writers for its precision and reliability, this refillable pen is a rare find in the US market, making it a must-have for professionals who demand excellence in every line.

## Description

The Uni Signo DX (UM-151) is claimed by some to be even better than the Pilot Hi-Tec-C! It comes in 0.38mm tip size. The barrel and tip are a bit sturdier than the Hi-Tec-C, which might explain why converts love them. 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.

Review: Quality - These are the best pens I've ever used, and when they finally dry up, I'll order more. I was first given Uni-ball Signo pens as a Christmas gift, and had to ask how I could order more colors (blue & black, for example) since they don't blob on the paper and are so smooth to use. Now I make sure I always have the Uni-ball Signo pens in red, blue, navy and black. Smear resistant, smooth, and consistent line thickness.
Review: My favorite - Excellent

### ⭐⭐⭐⭐⭐ Great Pen for Editing or Grading
*by G***Y on March 10, 2017*

These red pens are great for editing or grading. Ink flows smoothly, and the ultra-fine line makes it easy to squeeze in editorial marks or comments. It's not an all-purpose pen. You probably don't want to write pages and pages with it's needle tip, but for writing between lines of text it can't be beat.
