Although traditionally used for Japanese calligraphy, fude brush pens are great tools for all artists. The Kuretake Nihondate Kabura Fude Brush Pen No. 55 is a double-sided pen with a firm fine point on one end and a flexible rubber brush tip on the other. The soft brush tip is extremely flexible, making it easy to create thick or thin strokes, while the fine tip is stiffer, allowing for greater control. Filled with water-based dye ink, this pen is water-soluble and perfect for creating wash effects.
