Uni Pin Fine Line Drawing Pen, 0.1 mm, Archival Pigment, No-Bleed, Textured Grip, Ideal for Shading & Sketch Details, Light Grey – Pack of 12

A 0.1 mm tip produces very fine, crisp lines ideal for intricate details, delicate outlines, and precise hatch shading. It’s great when you want fine control and clean edges in architectural sketches, technical drawings, or delicate illustration work.

Archival pigment is a high-quality, fade- and water-resistant ink. It helps your drawings stay legible and vibrant over time even with handling, making it suitable for long-term projects, scans, and professional portfolios.

No—this pen is engineered to resist bleed on typical sketchbooks, planners, and grid papers, keeping lines clean and crisp even when you’re shading or layering.

The textured barrel provides a secure, comfortable hold, reducing hand fatigue during long drawing sessions and helping you maintain steady control in tight corners and along straightedges.

Yes. The pen uses a metal-clad tip designed to glide cleanly with rulers and stencils, helping you produce accurate lines without tip wear or snags.

This pen is best on porous papers like drawing paper, sketchbooks, and planners. It isn’t intended for non-porous surfaces (like glossy coated plastic) where ink may not lay down as evenly.

Keep the cap on when not in use to prevent the tip from drying out. Store upright or horizontally in a cool, dry place away from direct heat. After use, wipe any excess ink from the tip if needed and avoid pressing hard on the page to prevent accidental damage.

Yes. The Uni Pin Fine Line Drawing Pen uses archival pigment designed for safe handling and is formulated to be non-toxic with standard safety considerations for drawing implements.

Generally, a 12-pack provides better per-pen cost and ensures you have a consistent light-grey tone across multiple projects, making it a cost-effective choice for regular use.

Yes. Start with light, parallel strokes to build texture. Use a hatch pattern for shading and overlay multiple light layers to achieve midtones. Reserve the darkest lines for final outlines, then let each layer dry before adding more to avoid smudging.
