## Customer Reviews

### ⭐⭐⭐⭐⭐ These pens are SO GOOD
*by J***A on May 9, 2020*

I purchased the 0.38mm micropoint pens. They are magnificent. The lines are sharp, fine, I can write very small and the ball never gums up. I use these pens until they run out, and when I lose one I mourn. When someone at work asks to borrow a pen, I hand them an old bic pen if I don't like them... but if I do like the person, I let them borrow one of these, and I make sure they give it back. I've gotten a few compliments, and one person even asked where he could get a set! Ask yourself, when's the last time someone asked you where you got YOUR pens?They write very well. At first these micropoint pens tend to feel like they scrape the paper a little bit, but the writing is very fine and the ball never sticks (unless you abuse the pen). As you use the pen more, this scraping sensation goes away.I've also used the extra fine point (0.5mm), and treat them in the same manner as these pens. The extra fine point 0.5mm writes like a miracle... very smooth and silky lines. Buuut, after a few weeks the writing on those 0.5mm pens tends to bleed a little bit, and the lines get thicker. That is NOT something I've ever experienced with these micropoint 0.38mm pens. These pens write like a dream, from start to finish.

### ⭐⭐⭐⭐⭐ Favorite pens for work
*by M***  on January 4, 2025*

These are my favorite pens for work.I'm left handed and they do not smudge since they dry quickly. I continue to reorder these pens. I like the thin line they produce.

### ⭐⭐⭐⭐⭐ Superior to the Pilot G2.
*by V***N on April 20, 2019*

I'm a former Pilot G2 fanboy. Used those pens for years. I started having a problem with the fine point tip breaking and leaking ink all over. Thus began my search for the perfect pen. Through much research, and forum surfing, I heard mentioning of a legendary pen called the Uniball Signo. This pen has everything I loved about the G2, with none of the drawbacks. Ink flow is smooth, zero smudging, the .38 tip gives a very fine line and unlike the g2 isn't scratchy or skippy.As an added bonus the white color is rare, pen enthusiasts comment on it regularly, and even during the mundane drudgery of daily life people who use my pen compliment it. I usually get a "wow dude, that's a nice pen." Daily. Cool story bro.But seriously, these pens are awesome.
