DescriptionSpecifications
Uni-ball Signo gel ink pens are known for their smooth writing and exceptional ink quality. And, to everyone's delight, there is a sea of colors and tip sizes to choose from. Find the perfect pen for any task, whether it's writing meticulous notes, marking your calendar, or decorating your scrapbook with colorful captions.

Everything about this pen, from its solid construction to its carefully-formulated ink, ensures a wonderful writing experience. The sturdy tip does not bend or break, even with heavy-handed use. The pigment-based ink flows smoothly and is waterproof, fade-resistant, and feather-resistant. Much of that is due to special viscous properties of the ink. The ink is viscous while in the barrel, but as it passes through the pen tip during writing, the viscosity drops. This results in smooth ink flow. Immediately after it hits the paper, the ink returns to its viscous state, which prevents feathering. You are left with beautiful clean lines that you can enjoy for a long time!

THESE PENS ARE JUST INCREDIBLE! THESE ARE ALMOST AS TINY-POINTED AS THE 0.18 BITS AND A GREAT DEAL SMOOTHER. IF YOU ARE WRITING ON LOW GRADE PAPER OR PAPER THAT HAS BEEN PRINTED, YOU ARE BETTER OFF WITH 0.38 dx.
