I love bold thick lines

Write smooth fine lines and they don't leak.

These pens at amazing - comfortable grip, and smooth ink flow with nice line thickness

I prefer thinner pens with super fine lines

The ink also tends to "spread" when writing on cardstock and construction paper in that your lines turn thicker and fuzzier a few seconds after you've drawn them.

They have the perfect line thickness for reading and they write so smoothly

He's a leftie - and I must say it's true, when he has one of these pens there are no ink smears all over his hand like usual (even if he uses pencil he gets smears all over him, so these are fantastic for him)I used to avoid gel and liquid pens in general because of the smearing and running and glopping, but this one gives a clean line every time, even when I get stuck midsentence and pause for a moment there is no big glop of ink or bleed through the paper mess

But if you like the bold line it is very good.

No smear, smooth lines.

I like the thicker lines of the .7mm tips.

(I only tested the black one.)For a colored clicky gel pen, I much prefer the Zebra Sarasa Gel Retractable , which is more consistent, skips less, and lays down a darker line: http://www.amazon.com/gp/product/B0000AQNW5/ref=cm_cr_ryp_prd_ttl_sol_2

I genuinely appreciate good quality, smooth writing pens that provide clean lines and don't bleed or smudge

Better than those odd contortions that change width every cm along the barrel with protruding grips and such).Effortless writing, just touch the paper and it makes strong, definite lines

No smear, smooth lines.

Accurate lines

Clean lines, quick drying and never any skipping

If you like a wide line (as I do) make sure you try the 1mm inserts

The color is bold and solid, creating perfect lines and handwriting with the 0.7mm tip

Very smooth writing and makes a nice bold line but not too bold

Nice clean lines - very smooth.

Very smooth even lines

nice pens nice colors writes fine lines
