Product Review

The pigment ink is used. It is strong in fading by light. The ink does not blot to water. A vivid line can be left long. It is excellent in resistance to water/light stability. Because the line does not fade easily, memories written in the diary and the letter remain long. It is an extra fine type whose ball diameter is 0.28mm. Because the viscosity of ink decreases by the turning force of the ball, it can be written down that it is smooth. The viscosity rises as for the ink written on paper by the character to start returning like former gel, and the blot of the line decreases.
