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.
