The line is so thin, and the color so pale, it just fades away.

Always a good dark line

Clean, bright lines.

These pens provide that dark line, don't break, don't uncap in my pocket and are generally pretty great

These pens have an extremely fine needle point, which makes very thin but dark lines

The pens have a fine enough line of even ink distribution to be suitable for note taking and letter writing

They offer a nice, crisp line and lovely flowing black ink

Fine lines and they last a long time!

These are by far the best:+ nice dark line that's easy to see and read, but not too thick+ not prone to skip (unless held upside down)+ comfortable grip (important when you write a lot, like me)+ see-through window lets you see how much ink is left, so you can swap pens instead of running out of ink in the middle of an important meeting, class, or lecture+ durable -- I've probably used up a couple hundred of these pens at this point, and never broken one+ ink resists water and fading (pages I wrote over 10 years ago are still dark and readable, unlike some other brands)+ if you spill ink, you can remove it with rubbing alcohol or hand sanitizerThe only real

pricey but gives smooth writing and consistent line.

These pens write extremely well, leaving a nice dark line

I like a good dark line for scribbling in my notebooks.

Silky smooth performance, with solid black fill and beautiful lines

The line is good and is variable with pressure

That is, you never really get an accurate line or pin-point precision

Very reliable line and quality flow.

The ink is dark and the line it makes a good width, not to thick or thin

Perfect lines, every time

Nice solid blue lines good for scanners.

Wasn't the beautiful thick smooth lines I am used to.

The 0.5mm are, in my opinion, very nice and consistent for precise line work, accuracy, and reliability

As long as there's ink remaining you get a thick dark line, meaning no lost time going back to rewrite, I would highly recomend to anyone anywhere.

They give a really nice inky black line that looks a little wet but dries very quickly

Beautiful writing, a little ink blotting, nice thinner lines than average.

They write easily, don't smear, and make a nice bold black line.

It is not a sharp point, but a perfect ball that writes a nice, solid line.

They are incredibly smooth to write with and produce great lines

Nice pens, good lines and good feel

Great fine line penRead more

Helps improve my penmanship due its roller, smooth ink, and solid lines.

They make a perfectly smooth line and the ink holds up to all sorts of conditions

Always a good dark line

The ink bleeds out into the paper, leaving big fuzzy lines

They aren't the finest line I have seen from a

You could even do this a third and maybe fourth time and the line will become increasingly darker (as well as carve a dent into your paper.

These pens provide that dark line, don't break, don't uncap in my pocket and are generally pretty great

The flow of the ink is just perfect - it creates consistent lines with just a light touch, and also does not bloat if you enter a meditative state and keep the pen on the paper for several minutes as you are trying to birth out an original thought for your latest writing endeavor

Nice fine line

because it’s not the extra fine point I expected, it makes markedly thicker lines and it bleeds through the paper

I am looking for a pen that writes VERY smoothly and makes solid, dark lines for everyday journaling

These are the best ever: clean, clear lines with no dragging or skipping

Smooth lines

It writes a nice, dark, skip-free line and dries quickly enough for me (a lefty) so as to avoid smudging

I am looking for a pen that writes VERY smoothly and makes solid, dark lines for everyday journaling

In my experience they make a more consistent line than a regular ball point and they are smoother.

Good ink with a fine line.

Cons:- Not as smooth as I hoped
