Uni-Ball Vision Fine Black

The Uni-ball Vision rollerball pen features the Uni-Flow ink system, which creates a steady flow of water-resistant ink and smooth, consistent color. The pigment-based ink forms an indelible bond to 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, fade-resistant, and of archival quality—ideal for valuable documents. Two windows on the pen barrel also help you keep track of how much ink is left.
