Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm - Black

Great value for what you're getting. Very smooth, very nice. I'd be using these instead of the DX if they had this in 0.38. I actually prefer the pen without the rubber grip, since it makes the pen look more minimal. Often borrowed, rarely returned. Get more than one.

there will no other gel pen as smooth as when you are writing with um-100. Although this pen may look ordinary but its performance can be compatible with world class gel pens. the advantages of this pen are: smooth handwriting, no skipping of ink, quite a long ink life, a non-tidious writing hand while using this pen. And of course, this a good pen with dark ink which most you guys will love it. Try investing one urself, you guys will go 'woah, smooth!'

This gel pen is smooth and has a lasting ink with cheap refill,except that it doesn't have any rubber grip. abit disappointed on this part. Nevertheless, THIS IS A GOOD SMOOTH AND CLASSIC PEN!

I have to blame this pen because I abandon my MONTBLANC starwalker. Why? Uniball Signo ink is so smooth that I can't find any pen that comes close. Just buy one and try it. The great thing of this pen is that you can write very well on any type of paper. I am extremely picky at paper. Only this pen can withstand the worst and the best of all paper and still yield beautiful handwriting. However, Mitsubishi did not make any high class pen based on this technology of ink. That really saddens me.....

Great smooth writing pen with dark ink.
