Characteristics of Blue Moss
Blue Moss is a blue ink made with oil-smoke, high-quality glue, and pure indigo (Indian indigo) developed over many years of experience.
When used thick, it has a strong grayish blue, while when used thin, it has a lighter, slightly brighter blue.
It's ideal for soft-feeling works, and is suitable for ink-and-sumi painting, haiku painting, and calligraphy.
