The Uni-ball Vision Needle Point roller ball pen is strong—it has a strong needle point ideal for precise writing, and pigment-based ink that forms an indelible bond to paper, ensuring document security. The ink color is bold, water-resistant, and fade-resistant. It is delivered in a steady flow through the Uni-flow ink system, resulting in smooth, consistent color.
Very nice pen with a very smooth feel...the line it puts down feels to me like a
0.50mm or so, which is not fine enough for me. I like this pen, but don't use
it for the really fine drawing that I like to do.
