While waiting for my second JetPens order (some mechanical pencils for my sister, Pentel Slicci 0.4mm and Pilot G-2 for me), I just thought of putting up here a sample.
From top to bottom:
Pilot Hi-Tec-C 0.4mm
uni-ball Signo DX 0.28mm
I got the Sharpie pens from Office Max and really like them, which surprises me since I was never able to find the right felt tip pen for my hands.
During grade 1-5 at home, we all had to write with fountain pens (the cheap Hero ones that always sprinkled extra ink), and I actually broke several of them. When I got to junior high school (grades 6-9) then senior high school (grades 10-12), we were allowed to use other types of pens, and I've been a fan of uni-ball since. A few stores there have been carrying the uni-ball Signo UM-100 pens and I rarely found any other favorites, partly because we did not have that wide of a selection in stationery stores and bookstores.
When I got to the States, my stationery addiction found its place to be.
I love stationery in general. Pens and journals/papers are the major ones.
