It is equipped with the world's first revolutionary newly developed ink, and compared to existing oil-based ballpoint pens, "JETSTREAM" achieves a smooth writing feel with low writing resistance regardless of writing speed. ■ Clear and Dark Lines: By combining new 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 penetrates the paper and dries very quickly. It reduces the stress of getting your hands dirty by touching the lines, which is common with conventional oil-based inks. ■ New Mechanism to Prevent Ink Flow and Backflow: Equipped with a spring tip & twin ball mechanism. A spring tip is built-in to accommodate the smooth, low-viscosity new ink. By pressing the ball at the pen tip, it prevents ink flow (leakage from the pen tip). Also, the twin ball mechanism prevents ink backflow (ink flowing against the pen tip direction). ※ Reference Price: 88 yen (tax included) 6 pieces = 528 yen (tax included) ※ Please purchase only if you understand that this is stored by an individual. ⭐︎ Shipped by regular mail (non-standard mail).
