Uni-ball Uni Pin Fineliner, 0.2 mm, Pigment Ink, Ultra Precise Tip, Archival, Smooth Writing, Ideal for Technical Drawing & Writing - Black

A 0.2 mm tip yields very fine, crisp lines suitable for tight grids and small text. It’s great when you need precise detail, but you may need a steadier hand and slower strokes to maintain consistent line width.

Pigment ink uses solid pigment particles suspended in the ink, producing long-lasting, fade-resistant lines. It’s waterproof on many papers and scan-clean, making it suitable for archival drawings and documents.

The metal-clad tip resists wear and deformation when used along guides and drafting templates, helping you maintain consistent line width over time and reducing tip damage from rubbing on hard surfaces.

Yes. The pigment ink is quick-setting, which helps minimize smudging during overwriting and produces clean scans without fuzzy edges.

Cap the pen firmly when not in use to prevent the tip from drying. Store in a cool, dry place away from direct heat. Use gentle, steady strokes; avoid pressing hard to prolong tip life.

If the flow slows, gently scribble on scrap paper to restart the ink, then continue with light, steady strokes. Always recap after use; if persistent clogging occurs, set the pen aside for a short period and try again.
