## Overview

The Uni-ball Signo DX UM-151 Gel Ink Pen 10 Set features an ultra-fine 0.38mm tip and a durable barrel designed for precision and longevity. Its smooth blue-black gel ink is favored by artists and writers alike, making it a rare and coveted tool in the US market for those who demand both style and substance in their writing instruments.

## 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: Para mi es el mejor en su clase. El color azul-negro es excelente, la punta de .38mm es ultra fina para escribir letras pequeñas o escribir en letra manuscrita en renglones delgados.
Review: The UM-151 is a pretty well-known pen so there's not much left to say about it. I've been using these for the past seven years and the only issue I've ever had was that they will stop working if dropped on the head. The only factor is price and shipping and those were both good.

### ⭐⭐⭐⭐⭐ Review
*by S***A on 27 December 2023*

Favorite pen to use. I can write very small letters and still see the clarity. Each pen is long-lasting with smooth and bold colors that don't fade over time. Also useful for writing kanji and other detailed characters, which is why these are popular where they are manufactured (in Japan). If your handwriting is of the larger size variety, you might want to avoid. Otherwise excellent for calligraphy, small and cursive writing, fast writers and quick note-taking.
