Uni-ball Uni Pin Fine Liner Lettering Set, Waterproof Pigment Ink, Black, DGY & LGY Brush, Ideal for Technical Writing & Drawing, Assorted Tip Size – Pack of 6

The pens come with varied tip sizes to cover outlines, fine lines, and bold accents, giving you options from micro to bolder strokes for detailed lettering and drawing projects.

Yes. The Uni Pin Fineliners use waterproof archival pigment ink that resists fading over time, helping your lettering and drawings stay legible and long-lasting.

Absolutely. The precise, metal-clad nibs and stable line widths make them ideal for technical writing, lettering, sketching, and detailed illustration work.

They work well on most sketch papers and standard drawing surfaces. For optimal results, test on a small area if you’re using specialty papers to ensure the ink adheres cleanly.

Allow a brief moment for the ink to set after applying a line. The pigment ink is fast-drying on typical sketch papers, but avoid heavy smudging right after application and keep artwork flat while drying.

Cap each pen when not in use, keep the set in its carry case, and store away from direct sunlight. Store nibs and tips clean and dry to maintain line integrity.

The pens use pigment ink designed for archival quality and general drawing use. They are formulated to be non-toxic and suitable for typical writing and art activities, but avoid ingestion and follow standard safety practices for writing instruments.

For comparable performance, consider options like the Staedtler Pigment Liner set (0.3/0.5/0.8) and the Sakura Pigma Micron Fineliner range. Each offers pigment-based, waterproof lines with different tip assortments and price points.

This set is well-suited for precise outlines, technical lettering, architectural sketches, line art, inking over pencil drawings, and any project that benefits from clean, waterproof lines with consistent width.

Nibs in fineliner sets are generally designed to maintain their width over time, and some models allow nib replacements. If a nib wears or you need a different width, check the specific product page for replacement nib availability and compatibility.

In most cases, buying a multi‑pack provides better value per pen and lets you choose the appropriate width for different tasks without buying each pen separately, making it a versatile and cost-efficient choice for both beginners and professionals.
