I bought these at a local...
February 28, 2015
I bought these at a local store around my house for two reasons, it had a lot of ink and it was a Signo. The 0.5mm tip bothered me somewhat as I usually use the Signos in the 0.28mm tip size. However, when I got home and began to use it, I saw that is was THE smoothest pen I had ever used in my life. The color was rich (probably due to the larger tip size) and the barrel was the perfect width. The pen is ridiculously long, longer than the UM-151's (Signo DX) by quite a bit. If they made this in a 0.38 tip size, imo that would be the perfect pen.

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!'
