What our customer's say!

"Went through the wash - clothes are still white!", Our office is stuck in the 80's - everything goes by fax. I audit a bunch of 80-200 page reports weekly and after dealing with the cheap Bics our office keeps buying for us, I went out and bought a 10 pack of G2 0.7mm's. For starters it writes infinitely more smoothly than a cheap $0.10 pen, and the thickness and blackness help make writing much more legible on faxes. The darkness of the ink and smoothness of the writing really makes the address 'pop' on handwritten addressed letters (yes, we do that by hand, too). I worked at a major office supply store chain and got to play with all the verious pens - besides a particular uniball that uniball doesn't make anymore, this is the best writing pen/cartridge i've experienced, bar none. I just put my clothes in the laundry and did a search on the pens and found out that while they're water gel based, they're VERY water resistant. A G2 fell out of my jeans as I went to put them in the dryer and I had a sinking feeling when I went to look and see what shade of gray my white shirts had become. To my suprise, after a half hour wash cycle, the clothes were still their proper color! I wiped the pen dry with a paper towel, and to my astonishment, writes perfectly! I always keep a couple at my desk and in my car, briefcase, etc. A+.

"It's just plain classic.", I always keep a few of these around. I am somewhat of a pen geek, and Pilot is my favorite brand, as it has been for many years. Sure, I sometimes like something different for a while (I've acquired a few Parkers lately) but I always seem to come back to Pilot. This G2 is one of those things that doesn't seem to change much over the years. These black pens are actually made in two different countries. (These are so popular in the U.S. that Pilot has been manufacturing the black G2 in the Unites States as well as in Japan).So what separates the Japanese original version from its American made counterpart? Nothing. Unless you look at where the pen was made, you cannot tell the difference. They are both reliable. Sometimes when my fancy pens are unreliable, I just go back to one of my trusty G2s and everything is good.
Incidentally, even my fancy pens including my best fountain pen and my high quality ballpoint pen are Pilot Knights. Incidentally, what is inside the rollerball/gel pen fancy Pilot Knight? A G2 cartridge, of course.
