Sign Artist Brush pen, this advanced brush pen is from Japanese Pentel. Imagine a strong watercolour in a pen equipped with a soft, ultrafine 6 mm long brush. The delicate tip produces a line width of 0.3-1.5 mm depending on how light your hand is. The ink is water-based, flows richly through the brush tip and almost requires the use of bleed-proof paper or paper with a high gsm. Once the ink is in place, you can continue to work with it with a brush and water. The pens are incredible tools for comic and manga artists, hand lettering and calligraphy, but they place quite high demands on the user. The line is part of the Pentel Recycology series, which means 81% of the plastic in the pen is from recycled material. Length 13 cm.
