* The Posca brush felt pen is appreciated and used by many audiences: artists who use it to color sculptures and castings, or hard-to-reach surfaces (between folds, in curves, corners, and holes), Art Toys enthusiasts to reach very specific parts of the object (under the arm, in the neck), lovers of Asian calligraphy for the brush effect combined with fine lines, illustrators, as well as beginners to easily get familiar with brushwork. You can spread the paint and sweep it across the surface to impregnate it, leaving a perfectly smooth line.
