Uni Pin Fine Line Drawing Pen, 1.2 mm, Bold Technical Tip, Archival Waterproof Pigment, Textured Grip, Ideal for Labels & Outlines, Black – Pack of 12

The 1.2 mm tip produces lines close to 1.2 millimeters wide, delivering bold, clearly defined strokes.

Yes. The pen uses archival pigment ink that is waterproof once dry, helping drawings stay readable over time.

The ink is engineered to be feather-resistant and designed to minimize bleed on layout pads, supporting clean, crisp lines even on busy pages.

It features a textured grip for steadier strokes and a reinforced nib designed to resist wear when used with templates and rulers.

Ideal for labels, outlines, diagrams, signage, and thick contour work on paper and layout pads, with reduced bleed on suitable surfaces.

The 1.2 mm version delivers bolder lines suitable for headlines and thick outlines. For finer work, consider the 0.5 mm or 0.8 mm Uni Pin pens available on Fepy. Examples: 0.5 mm option (https://fepy.com/product/uni-pin-fine-line-drawing-pen-0-5-mm-black-pack-12) and 0.8 mm option (https://fepy.com/product/uni-pin-fine-line-drawing-pen-0-8-mm-black-pack-12).

Architectural diagrams, poster labels, bold annotations in technical drawings, and any project requiring strong, legible outlines and callouts.

Hold the pen with a steady grip near the nib and use a ruler or straightedge to guide long, straight lines. The textured grip helps maintain control during longer strokes.

Cap the pen after use and store it in a cool, dry place. Keeping it capped helps preserve tip integrity and prevents the ink from drying out between uses.

Yes. The combination of bold 1.2 mm lines, archival waterproof pigment, feather resistance, and a durable nib makes it well-suited for professional labeling, diagrams, and bold outlines in design work.

The 12-pack gives you multiple pens, ensuring you have backups and ample supply for multiple projects or long-term work without interruption.
