Fude Pen Hoso-Taku, also known as Brush Pen No. 7, is a single-sided water-based dye. With a flexible felt tip, it can be used to create thick or thin lines with ease and works well with any writing style. Allows for great consistent lines and dark black ink color. The refill cartridge is interchangeable with the Kuretake Brush Pen No. 8 cartridge.
