## Overview

The Uni-ball Signo DX UM-151 Gel Ink Pen 10 Set features an ultra-fine 0.38mm tip delivering precise, clean lines with smooth, vibrant blue-black gel ink. Its sturdy barrel and reinforced tip ensure durability even under heavy use, making it a favorite among artists and professionals alike. This highly sought-after Japanese gel pen is rare in the US, offering a unique blend of performance and exclusivity for detailed writing, calligraphy, and fast note-taking.

## 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: Awesome pens! - I write a great deal at work and often need to write really small. I was nervous about the size .38 because I’ve never gone below a .5. I love these pens! They are the perfect size for what I do. The color is beautiful and shows up really well when scanning or copying documents (which is another thing I do a lot of at work.) They write as smooth as any other gel pen and don’t snag the paper. My only complaint would be that 2 pens out of the box (I haven’t gone through them all yet), dry up or get clogged so I had to through them away. Still a good pen for my purposes.
Review: Consistent ultra-fine Japanese gel pen - 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.

## Questions & Answers

**Q: How are these different from the uniball signo 0.38 UMR-1?**
A: These are not retractable, and If I remember the UMR-1 is.  Both are the 0.38 point size.

**Q: Are these pens retractable?**
A: No, you remove the top and the pen  point is ready to use.  You replace the pen top to prevent ink marks.

**Q: Why are these no returnable?**
A: Their the best pens on the market, I have used this for over 18 years and not once ever had a need to return them. Plus the ink flows smooth

**Q: Is the ink waterproof?**
A: Mine has never been wet. But it does not smudge

### ⭐⭐⭐⭐⭐ Best fine-tipped pen ever!
*by C***I on February 12, 2025*

When I was in high school, I had used them and have never found any other pen that came close to this. I'm glad I bought them through Amazon because these pens write so smoothly and last a long time. I love how fine the tip is. It dries quickly after writing and doesn't smudge. I highly recommend them.
