Uni-ball Signo Bit UM-201 Gel Ink Pen - 0.18 mm - Blue

Thanks all for posting reviews - entire site full of helpful reviews.
After testing out all I ordered, I found 95% of all the reviews (on products I ordered) to be very correct.
This particular pen, takes my breath away - OMG !!!
I just wouldn't recommend it for everyday use as other reviewer reported.
I can use it every other day!
Truly the sharpest, cleanest ink line possible. Many uses.
AND I tested it with several types of paper, all showed very little change with water applied. Testing water plus abrasion - the paper fibers rolled off before the ink budged. So I'd certainly say it is permanent on paper.

This pen is fantastic - but it's not for everyday writing. It works best on moleskin notebooks and I find it works wonderfully for putting notations in the margins of my Bible. Also great for other areas that may be small and need to be written in. I have so many kids and things I have to keep up with, I use this pen for my pocket calendar. I can get four or five activities on one day that way. It flows nicely, doesn't clog up, and after awhile if it seems like it's not flowing well, check the ink level.

These .18mm pens are perfect for the Kokuyo Campus High Grade MIO paper notebooks! The paper is so smooth that these delicate pens feel right at home.
