Review: A experiência foi favorável nos produtos aquisionados.
Review: The only pens I’ll use are Uniball. My fav the gel 207 impact is phenomenal, but this time around I decided to try a ball point. First thing I noticed was these aren’t as wide and bold as the 207 impact. They call it 1.0mm, but side by side you can clearly see this line isn’t as wide. I’d call it .7mm. What I do love is they are SMOOTH. They also will write on nearly anything and no smudges. The one thing I don’t like about gel. This ink dries as soon as you lay it down. The grip and feel is exactly what you’d expect from uniball. I’m also a fan of click on and off which these are vs pens with caps.

## 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.

These are the only pens that will still work after sitting in my car for any length of time. Pressurised and they work.
