## 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: 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: 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.

## 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

*by G***G on 20 April 2022*

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.
