Review: 書きやすいです。細かい字にうってつけ！もうコレ以外は使えないです。とにかく書きやすい。
Review: I'll admit it...I'm a pen snob. I love writing (both the craft of forming letters with a good pen and the art of expressing myself on paper). No doubt, that is why I enjoy writing product reviews. However, when I write, I want a good pen in hand. Sure, often I compose at the keyboard. However, when I have writer's block, I pick up a good pen like this Uni-ball Signo Um-151 Gel Ink Pen. It just seems to get my creative juices flowing. The first day, I noticed the tiniest hint of scratchiness with this pen. After using it for a short time, it seemed to go away. Either I broke the pen in, or I got used to it. Whatever, I adore this pen and all its features. I recently tried these Uni-ball Signo Um-151 Gel Ink Pens for the first time. I thought I had tried almost every micropoint pen on the market. Obviously not. These pens are absolutely fabulous: . 38 mm micropoint . metal tip . gel ink . no smudging or leaking . open Es, As, and Os no matter how small you write . instant drying ink . smooth writing/beautiful lines . comfort grip . round barrel . snap on cap . pocket clip . long lasting .very reasonable price ($1.50 a pen) This is a five star pen in my book. I'm going to have a hard time finding a pen that can beat this one at this price. Very highly recommend to other lovers of micropoint pens! Love it!

## Questions & Answers

**Q: Are the pens sent, the exact pens by Mitsubishi?**
A: No they were not. Similar ones but not those pens. What do we do about that?

**Q: My pens do not have a "DX" written on them, and there is small Japanese writing above the ".38" on the clip. Are your pens like this?**
A: Yes. I have just purchased one thousand of these from Japan. The new pens do not have DX written on them. They have uniball signo,  0.38 and Japanese writing written in orange on the cap. The pen itself has um-151 and .24 printed in black on the side. it has number 4902778556108 and 150 printed on it. I hope this helps!

**Q: Do these pens smear when highlighting over it with midliners??**
A: They do. Even if you let them dry for a little while (say going back to review notes after a couple days) they still smear. I usually highlight under my writing. These pens are gel so they’re bound to smear

**Q: Are these waterproof?**
A: These pens are not water-proof. While the pen's shell and grip are resistant to incidental contact with water, the tip of the pen is not. 

Avoid exposing the pen to liquids under extreme temperature or pressures.
Avoid exposing the pen to corrosive chemicals.
Do not submerge the pen in water. 
Do not attempt to write underwater with this pen. 

Contacting the pen's tip with very hard water may result in jamming of the tip's mechanism with crystal deposits, which may cause uneven or no ink release. Attempting to clear this by tapping the tip on a hard surface may clear it, but will result in breaking the tip.

### ⭐⭐⭐⭐⭐ Review
*by C***E on 30 October 2024*

I've been using Uni-Ball One Gel 0.38 pens for some time as well as Pilot Juice Gel 0.38 pens. But as they're pricey, I decided to try the Uni-ball Signo DX. I like the flow of the Uni-ball Signo DX way more! The flow isn't constant with the Uni-Ball One Gel or the Pilot Juice Gel 0.38, whereas the flow is more constant with the Uni-ball Signo DX. The black pigment is the same among the three pens. Overall, for the price, the Uni-ball Signo DX offers excellent quality!
