## Overview

The Uni-ball Signo DX UM-151 is a premium 0.38mm gel ink pen known for its ultra-fine precision, durable construction, and smooth, smudge-resistant black ink.

## 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 these pens, coworkers are hooked! - I’ve been a fan of these pens for awhile, perfect for those who are writing small. My coworkers have stolen some from me overtime and went on to purchase their own haha. Definitely repurchasing!
Review: I found my true love - After receiving this pen from the box and test it out, I was very impressed with the tip and the comfort, I didn't really notice about the thickness because I usually use gentle flicks to add details. Pen quality is average like the plastic feels strong. I recommend for people who likes to sketch and write (it doesn't smear)

## Questions & Answers

**Q: Is this pen retractable?**
A: Not retractable but it is the best pen I have ever used, no ink globs yet and I have gone through two packs so far.  The pen has a removable cap with an atypical clasp.

**Q: Is the pen with the label "umr-1" and the pen with the label "um-151" the exact same pen?**
A: The pens I purchased carry both labels on them.  I am not aware of pens with just one of those two label references.

**Q: Do these ship directly from Japan?**
A: Yes

**Q: Is this fake? Because I have the original one from a japanese store it doesnt have the chinese symbol on the cap.**
A: Not sure what you mean by "fake".  I've purchased and repurchased these wonderful pens through Amazon and this dealer, no problems.  Mine show Japanese symbols on the pen shaft, not the cap.
