Uni Pin Fine Line Drawing Pen, 0.9 mm, Archival Pigment, Water-Resistant, Low-Bleed, Ideal for Labels & Outlines - Black

0.9 mm tip for bold lines; archival pigment ink; water- and fade-resistant; low bleed; metal-clad tip suitable for rulers; ergonomic barrel texture for improved grip and accuracy.

Ideal for labels, borders, and clear mark-ups on planners, drawings, cards, scrapbooks, and other paper projects where strong outlines are needed.

The 0.9 mm tip yields bolder lines suitable for emphasis and edging, the 0.5 mm size offers a medium line weight for cleaner outlines, and the 0.3 mm size is best for fine details. See these alternatives on Fepy here: 0.5 mm: https://fepy.com/product/uni-pin-fine-line-drawing-pen-0-5-mm-black and 0.3 mm: https://fepy.com/product/uni-pin-fine-line-drawing-pen-0-3-mm-black

For clean, straight lines, place a ruler firmly against the paper and use the metal-clad tip to guide the line. Apply gentle, even pressure and let the ink dry briefly to prevent smudging. The design supports template use, making it suitable for borders and precise outlines.

Yes. The ink is archival pigment, offering water- and fade-resistance to preserve labels and drawings over time. It is formulated to be non-toxic and suitable for standard paper surfaces used in labeling and outlining work.

The 0.9 mm tip is well-suited for bold lines and graphic outlining, making it great for comics, diagrams, and label accents. It’s less ideal for delicate calligraphy or ultra-fine detail work, which is better served by smaller-tip counterparts like 0.3 mm or 0.5 mm sizes.

This pen is designed as a complete unit with a fixed nib. When the tip wears or dries out, replacing the pen with a fresh unit is recommended to maintain consistent line quality.

Keep the pen capped when not in use to prevent the tip from drying. Store it in a cool, dry place, ideally with the pen horizontal or upright with cap on to minimize ink flow issues and protect the tip.

If you need bold, high-visibility outlines or labels, the 0.9 mm offers strong performance with archival-grade ink. For finer work or intricate details, consider the 0.5 mm or 0.3 mm options. All variants on Fepy carry the same emphasis on quality ink and reliability, with returns supported under Fepy’s standard policy.

The pen uses archival pigment ink designed for safe handling on standard paper. It is non-toxic and suitable for typical art and labeling applications. As with any pen, avoid contact with eyes and keep away from small children when not in use.

The ink dries relatively quickly on standard paper and is formulated to minimize bleed. To maximize stability, allow a brief dry time before stacking or folding printed pieces, especially when working with glossy or coated papers.
