## Description

Uni-ball Power Tank Ballpoint Retractable & Fine Ballpoint Pen Rubber Grip Type-0.7mm-black Ink-value Set of 10

Review: Great pen, equal to a fisher at a fraction of the price - I love these pens. I found them years ago when I used to travel to Japan and then forgot about them. I have several Fisher space pens but it's a real pain in the butt when you lose one of these because they aren't cheap. These are the equivalent in a throwaway form factor. They aren't so expensive that you cry when you misplace it or somebody walks off with it. It writes upside down and on wet things just like a fisher space pen without the exorbitant cost. They are comfortable and the fine point works very well, never clogs never gets scratchy. I love these, and everybody that tries one usually wants to walk away with my pen. If I like them I let them because at this price I can buy several at once.
Review: Excellent Pen! - Been looking for these for years--thank goodness for desertcart; because, I don't think they are available in stores anymore (at least none that I have seen). Wonderful ability to write upside down, under wet conditions and permanantly without smudging or smearing! Rubber grip is nice and is very durable! Wish it came in "wider version" for larger hands; but, "grip" is good. Also, didn't realize they were "fine point" when ordered; however, the "ink spread" was good and did not "skip" during "rapid writing" so was maybe a "positive" mistake as it "writes just as well and with a thinner line!" Nice "bulk" package, too, so I am "never without a good quality pen!"

## Features

- Ink is always pushed out by the pressure of air
- Ideal for the outdoors or the work which stands and comes out, since it can write also upward
- It is suitable also for writing to a calendar.
- Even if it writes quickly, it is stabilized and ink is pushed out.
- Writes on wet paper, upside-down, in temperatures down to -20 °C

## Questions & Answers

**Q: Will thease work good in a warehouse freezer  writing on paper**
A: Yes they do I have worked with them outside in the extreme cold outside

**Q: Does the ink fade, or is it archival quality and good for checks etc.?**
A: I have used these pens for years and love them.  I have never had any fading problems.  But, I can not state that they are 'archival quality'   But, I do love the pens, and I have papers 2-4 years old with no fading.

**Q: Are these 0.7? Description says they are, but picture shows 0.5.**
A: Of the pictures shown only one is showing up as 0.5 and it won't allow me to zoom in. I believe it might be an error showing the wrong pen. The other clear picture, that's zoom-able, is clearly showing 0.7. I don't recall ordering any 0.5 pens. I only have the 1.0 and 0.7 sizes. I still have a few dozen pens left. They never stop working until they completely run out of ink. I prefer the smoother 1.0 size personally. The 0.7 is great for when I need clear precise writing in very small spaces. Great pen!

### ⭐⭐⭐⭐⭐ Always quality
*by J***O on December 23, 2024*

The pen is amazing. The best part is writing in any angle and upside down. It had a decent weight. The pen ink flows very liberally, despite the small tip. Definitely my go-to every time.
