Product Features
It is less likely to cause ink stagnation.
Since the viscosity decreases when writing, the ink adheres firmly to the paper surface, making it difficult for ink to remain on the pen tip and forming ink pools.
High-quality carbon pattern design perfect for office use
It does not smudge even when wet with water
Since it is a pigment ink, it has excellent water and light resistance, resists fading due to light, and does not smear in water.
What is the following generation material, "cellulose nanofiber"?
Cellulose nanofiber is "Japan's first new material, " attracting worldwide attention in recent years. It is a new plant-derived material made by finely loosening the same pulp used in paper and other materials down to nano-sized particles, and research and application development is being promoted as part of the "Japan Revitalization Strategy" to turn forestry into a growth industry. By disentangling it finely, a fine-grained transparent gel is obtained, which is easy to flow out evenly and smoothly even from the small gaps in the nib of a ballpoint pen, and whose viscosity changes appropriately under various writing situations, resulting in a smooth gel that goes beyond conventional wisdom. You can get an excellent writing feel.
