uni-ball Jetstream Extra Fine & Micro Point Click Retractable Roller Ball Pens,-Rubber Grip Type -0.38mm-Black,Blue,Red Ink -Each 1 Pens/Total 3 Pens Value Set

These are my new favorite pens!!!! They write smoothly and don't filter through the paper in my calendar!

Uni Ball makes other fine roller ball pens with different color inks. Most have a fine point that is 0.5 mm and they write very well. The particular pens we are describing here have a finer point that is 0.38 mm. If one desires such a fine line, these are excellent pens.

The pens are awesome. They have a perfect fine tip. However, a bit of history for you (yes I am a nerd) -- Mitsubishi made the Zero that killed so many of our service people in Pearl Harbor and WW2. Therefore, I kinda wish I had known that before I bought them, because for the same reason I will never consider a Mitsubishi vehicle, I would rather not buy any of their products.

Uno de los buenos, he usado otros, pero como estos que compré, vale la pena, cada centavo lo vale... se que no te arrepentiras de tu inversión y ademas viene con tres unidades, color negro, azul y rojo...

I use these for writing in a logbook which needs to be precise and small. These work great and I've never had any issues. Most of what I used smeared, but these don't for whatever reason and that's been super helpful.

Writes well. Able to highlight almost immediately. Best pens in my collection.

I bought them due to the fine .38 size tips to takes notes in calculus and physics classes. I didn't like them at first because they wrote a little "scratchy", and the ink skipped here and there. I picked them back up a couple of weeks later and the initial issues that I thought I had disappeared. Very nice to diagram and work formulas in a fine line, some problems take the whole page and there is a need to write small and legible.

I got these pens as a well-regarded fine point ballpoint to compare to an assortment of gel pens I've purchased recently. Unfortunately, I'm not very impressed.First, let's get the pros out of the way. The Jetstream 0.38 is a very fine point ballpoint pen, and it does write a very fine line. It's only slightly thicker than a Hi-Tec-C 0.3. The ink is supposed to be water resistant, unlike a lot of gel ink pens, so that may be a reason to choose them. The point is conical and robust, and not a fragile-looking needlepoint like a Hi-Tec-C. It should work well on multi-part forms. The body is pretty solid, definitely better than a Signo RT1, though not as good as a good capped pen like a Signo DX.Now, for the cons. While they dry relatively fast, they do blob a bit (their fine point means they don't blob as bad as a broader point ballpoint does), and they do smear some due to the blobbing. Of the three pens I got, both the blue and the black ones exhibit starting problems (skipping when you start to write) and intermittent skipping problems, sometimes bad enough that they won't write again until you scribble some. The red one was much better, with no starting problems and minimal skipping, though. They're no more available than good gel pens, and only slightly cheaper.Overall, they aren't bad pens per se, and as ballpoints they do have the occasional strength over gel pens, but for me at least, their drawbacks don't put them ahead of a good fine point gel pen, like the Signos, Hi-Tec-Cs/G-Tec-Cs, or Sliccis, so I can't recommend them at all.
