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

Yes. The pen uses archival pigment that is water-resistant, helping your lines stay legible over time. It dries to a durable, smear-resistant mark on typical sketchbooks and cards.

It is designed for low bleed on sketchbooks and cards. Very thin or coated papers may show some bleed-through, so using higher-quality paper yields the best results.

Line width varies with pressure and stroke speed, providing hairlines to broader strokes in a single motion. It’s also template-friendly, working neatly around rulers and guides.

Yes. The pen has a textured barrel that enhances grip and control, helping you maintain precise strokes during extended use.

Absolutely. The brush tip prints clean lines around guides, making it suitable for headers, borders, and layout work.

Cap the pen when not in use to minimize evaporation. Store at normal room temperature away from direct heat or sunlight. If the tip seems dry, a gentle reactivation stroke on scrap paper can help revive the flow.

Yes. The archival pigment and water resistance make it well-suited for professional lettering and sketch work that needs long-term durability.

The MI-PIN200-BR-BK-1 model is designed as a disposable brush pen. When the ink runs out, replace the pen with a new unit.

Great for expressive lettering, decorative headers, accents in design layouts, quick sketching, and creating line variation around guides and templates.
