The Koi calligraphy pen by Sakura is a brush-style pen designed for expressive writing, modern calligraphy, and artistic lettering. It features a flexible brush tip that allows users to create varied line widths simply by adjusting the pressure applied while writing or drawing. This tip mimics the feel of a traditional calligraphy brush, making it ideal for fluid strokes and elegant letterforms.
The pen uses water-based dye ink, which flows smoothly and blends easily, allowing for watercolor-like effects if desired.
