Description
This Uni-ball Jetstream featuring a special low-viscosity “hybrid” ballpoint ink, the Jetstream combines the smoothness, waterproofness, and fast drying times of a ballpoint pen with the vibrant color and crisp, consistent lines of a gel pen. Its ink cartridges feature a special spring mechanism that prevents ink leakage, plus a twin ball in the back of the tip to prevent backflow. This multi pen comes with ink thickness of 0.7mm instead of normal 0.38mm or 0.5mm. This multi pen combines four colors of Jetstream ink – red, black, blue, green into one convenient multi pen—perfect for hardworking students and professionals.
