This water brush pen works by filling the barrel with water before use.



Remove the brush tip from the barrel, then either pour water directly into the barrel or squeeze it like a dropper to fill it about 80% full before reattaching the tip.



Pressing the barrel releases a small amount of water into the brush tip, allowing you to pick up color from solid watercolor paints and paint directly, or mix colors as you go. You can also brush over watercolor pencil marks or fountain pen ink to create beautiful soft blurs.



When you want to change colors or rinse the brush, simply squeeze the barrel to release water and wipe the tip with a tissue to clean it.



The brush tip is approximately 9 mm long — a round, fine-point tip suited to detailed work. Made from nylon, it glides smoothly and feels effortless to use. The pen is compact enough to fit in a pen case, and comes with a cap so you can put it away immediately after use.



No brush-rinse cup or water bucket is needed, making it easy to use anywhere — at your desk, outdoors, or on a café table — whenever you want to add color to your techo or sketch something on the spot.



This water brush pen pairs especially well with the AQUA Palette - Portable Watercolor Paint Set, also available in the Hobonichi Online Store.
