For the pen tip, we adopted the pilot's original '3-point support tip', which has three dents on the tip of a thin stainless steel pipe and a carbide ball with a diameter of 0.25 mm. The friction area is small and natural rotation is possible, and the writing taste is smooth. In addition, in order to realize ultra-fine writing width, we have developed 'Nanogel Ink', an ink that does not bleed on the paper surface at the same time as minimizing the ball.
Using ultra-fine particle size biopolymer that has reached the nano (one billionth of a meter) world, ink comes out smoothly even for an ultra-fine pen tip, and you can write clearly without bleeding.
