Best pen ever
These pens write without skipping, w smooth flow, in any orientation, from first touch on paper to last, and it's permanent ink, soon as it dries. This would be the cartridge in high end pens if the high end pens had better cartridges. You can see the ink level, and it works right to the end. These never blow up in pocket, regardless being on a plane or pocket or Arizona summer heat in a car. The unretractable ones were better for in pocket use, as the nib was retracted, and the retractable ones will sometimes self extend in pocket, so not as safe in pocket due to pointy end, but they haven't been avail for a while. The 1.0mm is great for writing, the .7mm is great for fine drawing, etc. Only pens I will buy and have been buying for over 10 years, and I make my living by the notes I take. The only pens you will ever buy again once you try them. They don't look like a million bux, but you can make a million bux w them, without losing that comma that other pens sometimes don't quite write right. Right? Right.

Great pens.
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.

I agree - best pen ever!!!
I have been self-employed, working out of my home office, for over 25 years. So I have to provide my own office supplies with no employer to buy them for me. I go through a lot of pens in my work. I've tried about 25-30 different pens over that time and none have come close to the performance of these pens. Flawless performance - write first time, every time. No drying up, they write on almost anything, and they can even write vertically like on a list posted on a board or fridge without having to take the list down and put it on a dry, horizontal surface to write on it, like you have to do with all other pens I've tried. They are hard to find; even office supply stores don't carry them anymore. I can only find them here on Amazon. They're expensive, but worth it! They're expensive compared to regular pens that don't write inverted. But compared to other pens that write inverted, plus they add features worthless to me like able to write in space or underwater, these are far cheaper. I feel like I should hoard a bunch of them since it seems all the best products get discontinued. But even the ink in these great pens will eventually dry out, so it's not a good idea to stockpile them. All inks, dyes, paints, etc. have a limited useable life span. Just have to hope that I can continue to find them here.

They write at any angle
This is my go-to pen of all time! I like to do crossword puzzles in bed before I go to sleep, and I had trouble with other pens not writing at that angle. These pens are perfect. They write every time, and the ink lasts a long time. I have them sitting all over the house and carry them in my purse. They write right away - you don't have to shake them or scribble a bit to get them started. I've reordered them more than once. The only criticism I would have is the clip is a bit awkward and in the way of a smooth hold. Wish the on/off clip was shorter or not there at all; maybe just a push down on/off from the top of the pen.

I purchased these as they're able to write on wet paper and upside down. I have this with my field notes that uses waterproof paper as I find myself needing to jot down notes in all weather conditions, including in the rain. There are other pens on the market that offer the same features, but the uni-ball power tank is cheaper and, to be honest, much nicer to write with. I recommend this pen.

Scrivono sempre e in ogni condizione. E' il secondo pacco che compro non è mai capitato che perdano inchiostro. Le uso soprattutto per scrivere le parole crociate a letto quindi scrivono anche rivolte verso l'alto.
