Sakura Pigma Calligrapher Pen series is specially designed for calligraphers and letterers of all skill levels. Unlike most calligraphy pens whose nibs wear down with use, resulting in inconsistent, increasingly heavy marks, the Pigma Calligrapher maintains its ability to consistently create sharp, smooth lines and letterforms. Invented by Sakura over 30 years ago, Pigma ink is still the most reliable permanent ink on the market. A water-based formula of pigment-based inks, more complex than dye-based inks, chemically stable, water-resistant, and fade-resistant. The Calligrapher Pen eliminates cost barriers and equipment requirements for beginners just learning calligraphy, and offers an easy and quick alternative to traditional calligraphy pens for professionals.
