Writing with these pen is smooth. The flow on the paper when writing. I highly recommend these pens. My co-worker are alway trying to steal this pen from me. They like the way it writes.
I do a lot of writing by hand both as a biologist taking field notes in rough and remote terrain and as an author penning and editing manuscripts. I have basically given up on ball-point pens. They just aren't made the way they used to be. For decades I got along just fine with good old Paper Mate medium point black stick pens. They seemed to give me a darker less tentative line than Bic sticks. Then PM just stopped making them and every basic working class pen they've come up with since seems to glob ink. I tried everybody's ball point I could think of and they all seemed to either glob ink or to struggle to leave a dark enough trail. I don't know if it's the design or the manufacturing process for modern ball points but they all seem to lack the basic consistent flow that ballpoints of the past had. I tried a few other gel pens but may of these are slow-drying. So far Tru Red 0.5 mm seems to give me a fast-drying non-smearing non-globbing line.
