Simple pen, with amazing ink
Thank you customer service. I got the 0.5mm version & they were great! My immediate favorite & I have a lot of pens. I got a bad box of the 0.7mm ones & they were not so great. I got an old box that was obviously sitting around for a while. Customer service sent me a brand new box & they work beautifully!!! They write so smoothly. I use them to draw. Thank you!!!

For the price..
So they write nicely on this spiral pad but not so great on my recycled paper notebook, I'm not sure if it's just the paper quality or type of paper but they are definitely smoother on this notebook. For the price they are pretty good. Definitely a thinner pen so if you like a hefty pen and grip don't buy these. Very fine point. Dark bold ink flow. Comparable picture to two other style pens.

Great pen...tried many and always come back
I am always worried that uni-Ball is going to discontinue these pens. I have no idea how many boxes I have bought or even how long I have been using these - at least twenty years. I love the way they write, no bleed or even excess ink. My handwriting is sort of a unique combination of architecture script and a doctor Scribble, I write fast and unlike so many other pens I have tried the ink never pauses, runs out, or bleeds at stops. I forget to put the cap on, no worries...write just the same. Leave a cap off for days or weeks, one alcohol wipe and it’s like a brand new pen...I tried the micro (.5 mm) and many of the things I love about this pen disappeared...the .9 mm is too fat and messy. Like Goldilocks the .7 is just right. I have also tried all the new gel pens whether from sharpie, uni ball, Sanford, and pilot...none have provided the benefits of this pen - needless to say my sons have plenty of rejects to use at school.Writing is probably one of the most subjective things humans do...even more individual than personal fashion or eating. If you are unsatisfied with your current pen, I can only advise that you give this pen a chance.

Too Thin For Writing
These pens are very slim. There was an older version of this pen without the Uniball ONYX branding printed on the tube, which was better. The pen writes smoothly, but it is too small to hold comfortably.

My favorite pens all the time
I like its sleek design, comfortable grip and its professional look. Using it since I was in Highschool and have repeatedly ordered and am still using it. It writes really smooth though my handwriting is not that great but looks good. It has a very consistent ink flow and gives me an inspiration and enhancing my mood to begin new task with new pen.
