## Overview

The Uni-ball Signo DX UM-151 is a premium 0.38mm gel ink pen favored by artists and writers for its ultra-fine precision, smooth black ink flow, and durable tip designed to withstand heavy writing. This pack of 10 pens offers a rare, high-quality writing experience that outperforms many competitors, 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: Love them - Best pens ever. They last, they are comfortable and they will help you with your messy hand writing
Review: Long lasting, very fine lines, comfortable to hold. - I wanted a nice fine pen for writing small and drawing fine details in diagrams and found these suggested a couple of years ago. I've now gone through 20 of these pens and have loved 19 of them. (1 was a little scratchy, the rest were as smooth as I could wish for) You might think 20 pens in two years means they don't last long, but that's not true. I write a lot. I know from having typed up my notes that I have written at least 200 thousand words in that time. And that's not including the pens people have borrowed from me and not given back because they fell in love with them too. It's difficult to get the 0.38mm in the UK, so I tried the 0.7mm too. It is wonderful and fluid, but the breadth of the stroke is such that it's for a larger writing style.
