This brush pen was designed by Sailor under the supervision of popular Japanese calligrapher Ryofuka to be both stylish and comfortable to use. The curved grip section makes it easy to hold the pen in the recommended position, about 3 cm up from the tip. Its water-based pigment ink flows smoothly and consistently from the felt tip, which provides excellent control and line variation. The Fude Nagomi pens are available in two types: the Standard Models, which feature body colors inspired by the nature of Japan, and the Ryofuka Models, which feature pink and red-toned body colors selected by Ryofuka herself. Each pen includes a pamphlet featuring calligraphy tips and examples from Ryofuka, demonstrating proper sweeping strokes and tapers.
