1. High-flow ink design, not easy to break the ink, ensuring a smooth and consistent writing experience.
2. The pen core has a high-precision spring-sealed pen ball, which is not easy to dry without using ink for a long time.
3. Neutral ink has neutral color, bright color, stable quality and will not faint in water. At the same time, the viscosity of the ink is just right, it is fast drying and it is not easy to penetrate the paper.
The smooth writing experience is derived from 0.5mm high-precision tungsten carbide balls, which are comparable in hardness to diamonds and are reliable and durable.
