Copic Multiliner Pens are fine quality inking pens available in a variety of sizes and styles. The pigment-based ink is waterproof and won't bleed or smear when used with Copic Markers. These quick-drying pens are ideal for anime, illustration, cartooning, pen-and-ink drawing, and other detail work. Copic's polyester nibs won't roll or bend, and they're housed in a durable plastic case with "click fit" caps that prevent dryout. They're great for use as a complement to Copic Sketch Markers. Copic Multiliner Calligraphy Pens have a crisp, straight edge with a narrow cross-section for making well-defined lines. Perfect for hand lettering and calligraphy, their richly pigmented black ink is great for dynamic writing both broad and narrow.
