As much as I love retractable clicker pens so I don't have to worry about losing
the cap, the Signo UM-151 in 0.5 is the smoothest, most reliable, and most
visually pleasing ink and body amongst all the pens I've used (Zebra Sarasa 0.3,
Hi Tec C 0.4, Signo 207 0.5 & 0.38, Jetstream 0.7 & 0.5, Uni Style Fit 0.38).
This blue is bright (unlike Sarasa's blue which is oddly closer to navy or
blue-black) without looking silly. I look forward to using this pen for many
years to come and just continuing with refills.
