## Questions & Answers

**Q: I'm assuming this isn't a gel pen, rolling ball pen, or the smooth writing uniball signo pen?  I don't want it to smear.**
A: This is the greatest pen I have ever used. I started buying them when I did private security and had to write reports outside in the rain. This pen, the Power Tank, will write in sub-zero temps, upside down, and even under water. I have never had it smear on me. I sent some to my wife when she went through Army boot camp and she loves them also. When she deployed for a civil mission with the National Guard one winter when there was an ice storm, she had the only pen that would write in the sub zero temps... It is an INK pen, not gel and it is a ball point pen, but it is hands down the greatest pen I have ever used.

**Q: The barrel of the pen is clear, but is the plastic tube the ink itself is in clear? Want to see how much ink is remaining and most are solid plastic.**
A: Of all these pens that I have used, the ink level is visible in all of the barrels. It is a dark ink line in the middle of the barrel. The ink line becomes shorter as the pen is used and disappears when ink is used up.

**Q: Do these pens have a 0.7 or 1.0 point? Thanks!**
A: 1.0mm point. It writes a real nice (perfect for me) width line. It doesn't run out wide like a felt tip pen does. The thick gel stays put and the pressurized tank writes upside down and on demand, 1st time, every time. Only negatives are the short ink life and the extra barrel width.

**Q: Can it write well on carbon copy like checkbooks or forms that need to press through?**
A: It will definitely perform well on checkbooks that have to be pressed through. I don't have any carbons, but I'm sure that will work as well. We have used these pens for at least 8 or 10 years. My wife is a cross word nut and says she needs to be able to write over her. I like the pens for everyday stuff. They are made in Japan by Mitsubishi according to the box. Hope this helps.

### ⭐⭐⭐⭐⭐ Thing of EDC Beauty.
*by R***N on 21 August 2017*

Now, I'm a fanatic about my pens and recently I was investigating the space pen market for my EDC purposes... I wanted something that would write anywhere and everywhere. Personally I find the Space Pen refills to be overpriced and my normal, day to day, go to pen is the Uniball Signo Micro Fine in blue. It writes like a dream and gel is just awesome. So when I found out that Uniball made a similar pen to the Space Pen I had to give it a try... This pen writes on everything. Smooth and steady, I had it writing on pieces of flimsy, oily plastic. When I'm transferring designs over to brass plate, this writes on it with no difficulty OR smudges. No skips. No need to go back over what I'd written. Upside down and it just keeps on going. Nothing I've thrown at this has phased it. I'm tempted to stick one in the freezer and see how it operates after. This met all of my expectations... but one. The exterior isn't as functionally sleek as my beloved Uniball Signo RT. It's a little too bulky. The grip is too plasticky. And unfortunately the refill isn't designed to swap between the outer casings of the two pens. Uni ball, this pen is awesome but you missed the mark but not making it interchangeable with your Signo's.
