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 colorants and pigments, it achieves approximately twice the black density of conventional ink (black ink). ■ Excellent Quick-Drying: 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. To accommodate the smooth, low-viscosity new ink, a spring tip is built-in. 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 direction of the pen tip). ※ SXR-80-07 / SXR-ML-07 (Black only) ・Reference Price: ¥110 [SXR-80] (Excluding tax ¥100 [SXR-80]) ・Ball Diameter: 0.7mm / ・Ink Color: Black ・Order Code: SXR8007K.24 ・JAN Code: 4902778292426 ・Reference Price: ¥110 (tax included) 6 pieces = ¥660 (tax included) ※ Please purchase only if you understand that this is personal storage. ⭐︎ Will be shipped via Yu-Yu Mercari Mail.
