Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - Blue Black

I find the 0.38 mm version to be a sweet spot of fine, concise lines and ease of writing. The blue black ink is a fantastic alternative to the usual black but still professional in appearance to be used in a business setting.

This is the sweet spot. The .38mm is not too thing or too bold. I found .4 to be too thick and .3 to be too thin. 0.38mm seems to be the sweet spot.

Also, as far as the color, its just the right amount of blue where it doesn't hurt your eyes but its enough blue to distinquish it from black.

Its the best!

The perfect everyday pen for jotting down songwriting ideas in my pocket Field Notes. A great combo for remembering ideas, phrases, etc. rather than trusting my memory or slips of paper. Great for journal books too, which I use to flesh out lyrics. The ink flows fluidly smooth, lays down a nice fine line with no scratchiness. I love these pens, almost as much as my fountain pens. Maybe more because I use them everywhere.

I started with green-black; which still has not run out of ink, even though I've used it every day for almost a year! I have since bought more; green-black, blue-black, bordeaux-black and brown-black. The black ink tones down the colors - they have become my signature pens. The only problem is that folks tend to "borrow" them. But at this price I can easily afford to buy as many as I need.

BTW - As an old-school songwriter I really love to put pen to paper. I buy all my writing tools from JetPens. You could say you guys rock, literally.

these pens are my pride and joy. ever since i accidentally stumbled upon one a few years back, i was hooked......to the point where i absolutely refuse to use any other pen. NO JOKE. my boyfriend thinks i have an unhealthy obsession with the pens, but i gave him a set to test out and he seems to be secretly enjoying them himself as well....=D

PEOPLE, you have to invest in one to see for yourself.

I love this pen! I first purchased one of these pens while studying in Hong Kong, and was impressed with the efficient, durable design. But when I got back to the States, I couldn't find the pens or refills anywhere. I stumbled across this site, and ordered a big box so I wouldn't run out again.

The tiny carbide steel ball (0.28 and 0.38 mm) means less ink is wasted compared to the American Signo line. At the same time, it writes as smoothly as a regular gel pen. My only regret is that I can't purchase them in bulk.
