If you didn't know this already I am a big fan of orange. Orange pens, orange barrels, orange inks, orange detailing, pretty much anything orange. There is no real reason why, other than the fact I am not a fan of red, so I use orange as my red replacement.
What I have never been a huge fan of is the Pilot FriXion line. They are completely fine pens, but usually not for me. They are growing on me though, especially as the product line matures. I think the turning point for me was the FriXion Biz, which is the only FriXion I use regularly, but the recently released Pilot FriXion Ball Slim may join the club.
The Slim has two things going for it: An ultra-fine 0.38 mm tip, and a slim but comfortable barrel design. I like these slim single cartridge barrels more than I ever thought I would, starting with the Uni-ball Style Fit. The FriXion Slim feels great in the hand and is very manuverable. The knock is placed subtly on the side of the barrel allowing for the eraser to be placed properly on the top of the pen.
I think the 0.38 mm tip is even finer than that. It writes more like a Uni-ball Signo DX 0.28 mm to me. That means there is some scratchiness when writing, which should be expected on a pen this fine.
Where the FriXion runs circles around other pens in this category is erasibility. No other company can hold a candle to Pilot in this area, so if an erasable gel ink pen is what you need, look no further than the FriXion.
