"Addictive, smooth writing experience. The 'Jetstream' multi-color and multi-functional replacement ink cartridge features: ■ A revolutionary ink that achieves a smooth writing experience with low writing resistance, making it the first of its kind in the world. Compared to existing oil-based ballpoint pens, 'JETSTREAM' provides a smooth writing experience with low writing resistance regardless of writing speed. ■ Clear and bold lines. By combining color materials and pigments, it achieves approximately twice the black density of conventional ink (black ink). ■ Excellent quick-drying properties. The newly developed ink easily absorbs into paper and dries quickly, reducing the stress of getting ink on hands, which is common with traditional oil-based inks. ■ mechanism prevents ink leakage and backflow. Equipped with a spring tip and twin-ball mechanism. To accommodate the low-viscosity ink, a spring tip is built in. By pressing the ball at the pen tip, it prevents ink leakage (leakage from the pen tip).
