Nice site with unique stuff. Bought a bunch of Plot G-Tec-C .25 mm and .30mm gel pens and a few of the Pentel Slicci .25 pens to try out. Been using the pilots for my small notebooks and they are fantastic for dark thin lines, small writing and small illustrations! Does anyone have favorable reviews about the .18 tip pens? Having gotten used to the .25 tips took a while, but now they are all I use for my tiny writing. Heard that the .18 tips are too scratchy and ink does not flow properly. The tip to using these hyper fine tips is to use hard smooth paper. I found the moleskin notebooks take the ink nicely. Smooth business cards are even better. I should try some write in the rain pads. I bet they would be great!
