If you want the finest line, buy the 0.5

Clean lines, no scratchy feeling while writing, dries quickly to minimize smears common to gel pens.

Love the thick lines and nice smudging.

A little fine line wouldn't hurt my feelings

These deliver clear lines without clumps, or stains on fingers

Clean, consistent, solid line

I like this line of pens.

Pentel in a bunch of juicy bright colors that lay down a nice wet line that dries immediately

If you like gel pens these are broad and lay down a nice and wet line.

In common ball points I have not liked the wide line of normal or .07mm tips.

smooth lines nice grip...great colors

Nice thick lines, and the pens are pretty, too

This is the first one that provides crisp clear lines and no smudges.

My favorite pen - clean lines and no smudging.

They write a smooth full line without skipping

This one is 0.7 and is like Sharpie's "fine line" marker (which is too thick to write in small boxes).

I've tried the less expensive competitor's gel pens, as well as Pentel's "Wow" line, but this pen is superior

Very clean lines, but bleeds through a bit and makes a pronounced ink line when first starting to write something.

I prefer the bolder .7 line and I prefer the needle tip, but that combination is hard to find

Clean lines, no scratchy feeling while writing, dries quickly to minimize smears common to gel pens.

These are nice and smooth, don't leak, and have a bold dark line.

Wonderful lines and always reliable

Nice bold distinct lines.

Received this one first and waiting for the finer line.

and oh I like the 0.7 line so much

It has the perfect line thickness for reading and writes so smoothly

They last a long time and provide a nice clear gel line.

They make a wonderful fine line one also.
