Imported from Japan, the ZIG Cartoonist Brush Pen No.22 has a medium nylon brush tip that lays down thick and thin lines. Move the pen slowly across the page for solid strokes, or move the tip swiftly across the page for a more diffused line. This brush pen is great for mastering cartoon illustrations or practicing bold hand-lettering. Run out of ink? The pen body cartridges are refillable for years to come.
