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 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). In addition, the twin ball mechanism also prevents ink backflow (ink flowing against the pen tip direction). ※ SXR-80-07 / SXR-ML-07 (Black only) ・Reference Price: ¥110 (tax included) [SXR-80] per piece (¥100 without tax [SXR-80]) ・Ball Diameter: 0.7mm / ・Ink Color: Black ・Order Code: SXR8007K.24 ・JAN Code: 4902778292426 ※ Reference Price: 6 pieces = ¥660 (tax included) ※ Please purchase only if you understand that this is a personal storage item. ⭐︎ Ships via Yu-Yu Mercari.
