Jetstream Standard Multi-colour Ballpoint Pen Addictive, smooth writing experience. This ballpoint pen is equipped with multi-colour ultra-low friction Jetstream ink. Low writing resistance, smooth writing experience Achieving the "Addictive, smooth writing experience" with a groundbreaking new ink development, Jetstream has reduced writing resistance to achieve a smooth writing experience regardless of writing speed when compared to traditional oil-based ballpoint pens. *Comparison of writing friction coefficient based on our company's test: The writing friction ratio of Jetstream when the writing friction coefficient at each load of our conventional product (oil-based ballpoint pen) is 100%. Measurement at a speed of 4.5m/min. Bold and vivid lines By combining new colour materials and pigments, it has achieved approximately twice the black colour density of conventional inks (black ink). Excellent quick-drying The newly developed ink easily permeates the paper, and drying is quite speedy. It reduces the stress commonly associated with traditional oil-based inks, such as smudging on contact and dirtying hands. Prevention of ink flow and backflow with a new mechanism Equipped with a spring chip & twin ball mechanism. To accommodate the smooth low-viscosity new ink, a spring chip is incorporated to prevent ink flow (leakage from the pen tip) by holding down the ball at the pen tip. Additionally, the twin ball mechanism prevents ink backflow (ink flowing in the opposite direction to the pen tip).
