Technical drawing demands ink that flows consistently and dries without smudging, Pacific Arc Blackliner pens deliver both. High-quality pigment ink resists fading over time, maintaining crisp black lines in finished work and archival drawings. The formulation conforms to ASTM D-4236 standards, ensuring safety for studio and classroom use.

Eight point sizes, from hair-thin 0.05mm to bold 0.80mm, let you build line weight variation without switching pen types. Fine tips handle intricate details and cross-hatching; broader points establish outlines and fill larger areas efficiently. This range supports everything from architectural renderings requiring uniform technical lines to expressive sketches where varied weights create depth and emphasis.

Each pen is sold individually, so you can stock up on the sizes you use most rather than purchasing sets with redundant options. Illustrators working in ink, designers developing concepts, and drafters creating presentation drawings all benefit from the reliable performance these fineliners provide across extended projects.
