Sailor Fountain Pen CYLINT Black Stainless Steel The black coloring technology used for the stainless steel material of the Black Stainless Steel model is a decorative process that fixes the black color with a thin film, offering the advantages of being resistant to fading and staining. It achieves a deep black color while utilizing the metallic feel. Unlike plating or painting, there is no risk of peeling, and the "inherently black" material's coloring technology boasts excellent durability and weather resistance. It preserves the original texture of the metal while maximizing the sense of weight, functionality, and design, creating a timeless "unfading black" that elevates its status. The origin of CYLINT... It's a coined word combining CYLINDER and Intelligent (INT). Purchased for 60,000 yen. I am selling it to organize my collection as I have accumulated more fountain pens. The nib size is F (Fine). Please understand that returns are not accepted after purchase. Please provide a converter yourself.
