From a pen junkie - love it
I’m one of those hopeless believers that if I just find the right pen, my handwriting will be beautiful. This has resulted in me owning MANY pens. From 0.28mm to 1.0mm, roller to fountain, I have WAY too many. But out of all the brands I keep going back to oniball. They’re always smooth, good ink quality (no skipping), last long, I mean you can leave them in a closet for 3 years and they start right back up! I think I saw someone using this one on YouTube & had to try it. The smaller the nib the better I write in my journal so had to try a 0.28mm uniball. It was everything the 207 signo 0.7mm, with tinier lines! I like the design, the straight lines is more comfortable to me. Very lightweight. And reliable - just like all uniball pens I own. Very pleased, this is the smoothest 0.28mm I’ve ever used!!!

WOW - Sharp!
This is my first experience with an Ultra Fine tip pen, it has a good feel in the hand, it writes a "thin line", and I've NOT had ANY "blobbing" of the ink on the paper while writing. If you need to make really small "informational notes" on documents, or in your Bible, THIS is a great pen for you. The 0.28mm point is Ultra Fine and allows for very small, but legible, while writing in between lines or in the margins. My normal use pen is a 0.38mm (Very Fine), but still too broad of a line for really small lettering (regular "Fine" pens are 0.5mm or 0.7mm).

Great quality pen
Why did you pick this product vs others?: The small fine point of this pen made the decision easy for me. I really like the way it writes and how it feels when used on paper. This is my go to writing instrument for work.
