Uni Pin Fine Line Drawing Pen, 0.1 mm, Archival Pigment, Water-Resistant, Low-Bleed, Smooth Flow, Ideal for Subtle Shading & Micro-Detail = Light Grey

Tip size: 0.1 mm; color: Light Grey; ink: archival pigment with water-resistance; low bleed; grip/feel: textured barrel for better control; tip is metal-clad for template-safe use with rulers and guides.

Smooth, white or light-colored papers (e.g., sketching paper, planner paper, and lightweight drawing papers) typically yield the crispest lines with minimal bleed. For heavy ink builds or layered shading, test on a scrap area first and prefer heavier-weight paper to maintain clean edges.

For sharper micro-details, the 0.1 mm Light Grey excels over larger tips like 0.2 mm in fine line precision and shading control. If you need bolder lines for emphasis or outline work, a slightly larger tip (such as 0.2 mm) can be more forgiving.

Yes. The 0.1 mm tip is designed for fine shading gradations and delicate textures, making it well-suited for micro-detail work in drawings, architectural plans, and layout annotations without overpowering the page.

Prime the pen on scrap paper before use, apply light, consistent strokes, and avoid heavy pressure. Keep the cap on when not in use to prevent the ink from drying at the tip. Use on compatible smooth papers and store the pen horizontally or capped to preserve tip integrity.

The pen uses archival pigment ink designed for durability and fade resistance, with water resistance to help keep lines legible over time. As with most drawing inks, avoid ingesting the ink and use in a well-ventilated area.

Use it for micro-detail work, subtle shading, fine annotations in planners or journals, tiny lettering in technical notes, and precise line work in sketches where clean, light-grey lines help preserve page readability.

Cap the pen tightly after use, store it capped and upright or lying flat to prevent ink from drying at the tip, and avoid exposing it to extreme heat or cold. Wipe the tip if it indirectly contacts dust or fibers to keep lines clean.
