Select brush pens for lettering and illustration and maintain tips for longevity.
Brush pens come in nylon or felt tips and liquid or pigment inks. Nylon brush tips offer spring and resilience for calligraphy while felt tips provide consistent strokes for illustration. Rinse waterbased brush pens after heavy use and recap them to prevent drying. For refillable brush pens use compatible inks and clean the feed regularly. Store tips upright or horizontally per manufacturer guidance to preserve shape.
