Ever since the release of the original Uni-ball Jetstream in 2006, Uni-Ball has been gradually adding new models every year. The newest Sport colors have not only new body colors, but they are also now available in a 0.5 mm tip. The Jetstream was named after the high-speed outpouring of jet stream airflow from a jet plane. The goal was to create a smooth outpouring of ink from a pen onto paper. Uni-Ball improves upon this design year after year by decreasing the coefficient of friction of its Jetstream pens to create an even more smooth and comfortable experience. The pen features light and water resistant oil-based ink. Black, blue and red ink refills are available.
