The Uni-ball Vision Elite roller ball 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. The pen is airplane-safe—a protective reservoir inside the barrel keeps air from expanding in the ink tube, thereby preventing in-flight leaks. The sleek durable metal clip, bend-resistant stainless steel tip, and tungsten carbide roller ball enhance the look and performance of the pen.
This is my favorite pen to write with on any kind of paper. It gives very little
feedback or scratchiness and it lays down a very black and even line. I've been
using this more than my fountain pens and I find that it is smoother than my gel
pens and the smooth ink ballpoint pens that I own.
