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.
