## Description

"It writes smoothly and smoothly. "Jetstream" Retractable Single Color Refill Product Features: ■ Low writing resistance allows for smooth writing and smooth writing Compared to existing oil-based ballpoint pens, JETSTREAM produces smooth writing with low writing resistance regardless of the speed of writing ■ Crisp and Dark Drawing Line: By combining new colors and pigments, we realize the black density of the traditional ink (black ink). ■ Excellent quick-drying newly developed ink penetrates into paper, and dries much faster. Reduces the stress of getting your hands dirty due to drawing lines common with traditional oil-based inks. ■ Equipped with a new mechanism to prevent direct current and backflow of ink with a spring tip and twin ball mechanism. Built in spring tip to support new inks with smooth, low viscosity By pressing the ball on the nib, it prevents direct ink (leaking from the nib). In addition, the twin ball mechanism prevents ink backflow (reverse to the nib).
