The BLX collection of Uni-ball Signo 207 gel ink pens features intriguing dark colors created by infusing black ink with color. The pigment-based ink bonds permanently with paper, resulting in strong colors and document security. It is resistant to chemicals that can wash away dye-based inks, thus preventing check washing (a common method of check fraud). The ink is acid-free, water-resistant, fade-resistant, and of archival quality. You will also enjoy a comfortable writing experience, due to the textured grip.
Dimensions: 5.6 inches length, 0.4 inches diameter (14.1 cm length, 0.4 cm diameter).
This pen is my new favorite for use with a Moleskine. The ink flow is
buttery-smooth, but the .7mm point still allows for my medium-smallish
handwriting to be legible. The brown/black is easy on the eye, with more brown
than black. I find this tint is quite a bit more readable than than the true
black pens I usually use, such as the Pilot precise V5. But this ink is
incredibly slow to dry, slower than any other gel or rollerball I own. I imagine
Lefties will have problems with it. I have resorted to using a 3x5 blotter card
under my left hand to hold down the page of my pocket journal. But the pleasant
tint and supremely smooth feel (on Moleskine paper, at least) are worth the
hassle of slow drying ink for me.
I love the rich brown black ink in this pen. It is very dark but just brown
enough for you to see that it isn't black. I use it in place of my black pens
when I am tired of seeing black notes. The ink runs very smoothly and nice.
