KUROGANE Stainless Steel Black Color
The use of a new electrolytic coloration technology enables deep black coloration while maintaining a metallic feel.
Unlike plating or painting, this technology grows an ultra-thin black oxide film on the surface of the material and uses light interference to recognize the color, so there is no risk of peeling off.
The coloration technology is an integral part of the genuinely black material giving it excellent durability and weather resistance.
While retaining the original feel of the metal material, the "unfading black" that is the result of mastering dignity, functionality, and design raises the status and prestige of the pen and provides you with an uplifting experience.
It is a supreme masterpiece brought about by the daring spirit of challenge that always aims for the highest level, fusing reliable technique backed by tradition with new techniques that are actively adopted.
