Fans of Uni's Jetstream line of ballpoint pens can now enjoy the same excellent writing experience they've come to expect, but in fun vibrant colors. Jetstream's exclusive Super Ink is a low-viscosity, oil-based ink that combines the quick drying time of ballpoint pens with the color and smoothness of gel pens. These retractable pens are great for everyday use. The rubber grip makes it easy to write with for long periods of time.
