I'm on the Pilot FriXion "bandwagon". This is a close second to my Uni-ball but
the 0.5 is perfect because I write small and this doesn't lay down a lot of ink.
I will be replacing the black ink when it's done with the blue/black refills -
I'm obsessed with Blue/Black ink !
I am enjoying this pen! I usually prefer a 0.5mm point for daily writing but
this is comfortable to write with and "rattling" sound isn't a big deal for me.
I will be purchasing another just to have a "backup" pen body, this also takes
the refills for the Uniball Signo 207 BLX retractable pens - I am in love with the Blue/Black ink.
