Uni-ball Power Tank Ballpoint Pen - 1mm
I have been using these pens for years. I like that they work at any angle. I like that water doesn't dissolve it. I often make notes in text books and if I accidentally get some water on it, the note is still there.
I have quite a few different Uni-ball pens. I have 0.38 mm up to this 1.0 Tank ballpoint. I like them all. How I use one depends on the application.
