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.
This is a set of 5 colors: Brown Black, Green Black, Purple Black, Red Black, and Blue Black.
Dimensions: 5.6 inches length, 0.4 inches diameter (14.1 cm length, 0.4 cm diameter).

207 retractable. Yep, these are them. Wonderful value!
I absolutely LOVE these pens - both the colors and the way they write. The
writing is SO smooth and the colors, although nearly black, have a nice tinge of

I bought this pen at a local office supply store to make sure it's what I'm

beautifully, but I don't find it to be "permanent". I did some quick sketches
two days ago, and when I put a very light stroke of water over it today, it
still smudges. So while I will definitely carry this pen and use it for writing
and notes, I won't be using it for sketching unless the wash effect is what I'm
