Sakura Pigma Calligrapher Pen Series is specially designed for calligraphers and lettering artists of all skill levels. Unlike most calligraphy pens whose tips wear with use, resulting in inconsistent, increasingly heavy markings, the Pigma Calligrapher maintains its ability to continuously 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 about calligraphy, providing an easy and fast alternative to traditional calligraphy pens for professionals.
