is the fine or the micro the larger line?

The fine point tip is larger than the micro point tip.

What's the difference from this pen and the uni-ball Onyx Stick Micro Point Roller Ball Pens, 12 Black Ink Pens(60040)?

In my experience the Onyx Smooth Write Rollerball (mico point- 60040) is very similar, with the Onyx producing a slightly darker black mark. This pen has more of a "precise" feel and I put that in quotes because you'd probably have to be real picky to notice a difference, and others might totally disagree! Both flow beautifully, seem to run out of ink at pretty much the same rate and are a pleasure to write with.

Is the micro the finest point in the Uniball style ?

The micro is the finest point using standard ink, but if you like gel ink there is an ultra micro with a .38mm point. You can find them on amazon as well. I have not used them, I like the .5mm point of the micro roller ball.

Queste penne purtroppo stanno per andare fuori produzione e a breve non saranno piu' disponibili. Dico purtroppo perchè sono veramente fantastiche, in misura 0.5, adorate da me e dalla mia ragazza che siamo consumatori incalliti di penne. Non sbavano, durano e con un inchiostro veramente gradevole

These pens write with a fine, precise line and give a slight rough texture on paper, which I really like. It makes writing feel more controlled. The ink flows smoothly without skipping, and they’re leak-proof. They feel lightweight, have been reliable, and long-lasting, and have been my go-to choice for everyday writing or note-taking.

Now Uniball, preferred and used these pens when they were Faber-Castell pens. The fit in my hand and the feel were important, still is. As long as I can find these pens, I am content.
