The uni Jetstream sport pen is more than regular rollerball pen. As youd expect it gives you smooth, fast flowing writing, but the pen also has the fast-drying properties of a simple ballpoint ensuring less smudging, making it ideal for left-handers. This pen is extremely comfortable to use for both left and right-handed writers, and its retractable too. It also comes with the added benefit of uni-balls Super Ink, which is fade resistant, water resistant and tamper proof so its great for important documents and journaling. Its 1. 0mm ball offers a smooth writing experience and the pen is available in black, blue and red.
