Uni Pin Extra-Fine Fineliner Brush Pen, Flexible Brush Tip, Archival Pigment, Waterproof, Ideal for Lettering & Sketching - Black

The EF brush tip lets you go from hairline to bold by adjusting the pressure you apply. Light pressure creates thin, delicate lines, while firmer pressure produces thicker, expressive strokes.

Yes. The pen uses a waterproof archival pigment designed to preserve clarity long-term and resist water exposure after drying, helping your work stay legible over time.

It’s formulated for low bleed, making it suitable for sketchbooks and cards. For best results, test on a small area if you’re using very thin or highly textured paper.

The barrel texture provides a confident grip, helping you steady longer strokes and maintain control during detailed work.

Absolutely. The pen is tool-friendly and designed to work neatly with guides and rulers, making clean, precise lines easier when you’re planning layouts.

Ideal for headers, accent marks, quick sketch shading, calligraphy-style lettering, and illustrations where you want expressive line variation with durable, archival marks.

Keep the cap on when not in use, store in a horizontal position to maintain ink flow, and if the tip dries, recap and gently re-wet by drawing on scrap paper. Avoid extreme temperatures.

This EF Brush Pen is not designed for refilling. When the ink runs dry, the recommended option is to replace the pen to continue achieving consistent results.

Compared to a standard fine-line pen, the EF Brush offers flexible line variation with a brush-like tip while maintaining archival, waterproof pigment, giving you both precision and expressive strokes.
