## Description

The Uni-ball Jetstream pen is often referred to as being the new standard in rollerballs – unsurprisingly! Each Rollerball pen is filled with Uni-ball's high quality Jetstream ink. What makes this ink unique is its fast drying speed and lighter feel. Jetstream ink reduces writing friction by 40% with a highly lubricating solvent that gives it low viscosity, letting you write as fast as you think! Jetstream ink dries 9 times faster than the standard Rollerball pen, making it smudge-free. This rollerball pen is perfect for left and right handers with the smudge-free ink and rubberized, ergonomic grip. Jetstream ink also has the same benefits as Uni-ball's Super Ink, making it tamper-proof, fade resistant, and water resistant. Create bold lines with a 1.0mm ball, making it perfect for penning letters or writing in journals. The pen tip is retractable when not in use, and the entire pen has a sporty feel and look with a translucent barrel, comfortable rubber grip and white pocket clip. This set comes with Blue ink pens in a box of 12.
