Fineliner pen Sakura Pigma Micron 04 — red, 0.4 mm tip, permanent pigment ink

The Sakura Pigma Micron 04 fineliner pen in red features a 0.4 mm metal-clad tip and archival-quality permanent pigment ink formulated for precise line work. Designed for technical drawing, sketching, illustration and note-taking, the Micron 04 delivers consistent, even lines with ink that resists fading, water and bleed-through on many paper types. Its compact, lightweight barrel and snap cap make it suitable for studio, office and field use where stable, smudge-free marks are required.

Advantages

The fine 0.4 mm tip produces clean, uniform lines useful for detailed work and consistent lettering. Permanent pigment ink provides archival permanence, water resistance and low bleed, allowing drawings and documents to retain clarity over time. The pen’s reliable ink flow and durable tip reduce interruptions during drafting or sketching, while the red color offers clear visual contrast for corrections, annotations and emphasis without compromising line definition.

Suitable for

• Technical drawing and architectural sketches
• Illustration, inking and comic art
• Note-taking, diagramming and annotating documents
• Stamping, journaling and scrapbooking with archival requirements
• Precise outlines, hatching and fine detail work

When it may not be suitable

The Micron 04 is optimized for paper and similar porous surfaces; it may perform poorly on glossy, highly coated or non-porous materials where pigment ink cannot absorb properly. For very broad strokes or filling large areas, a broader or brush tip will be more efficient than the 0.4 mm fine point. While the ink is water-resistant, it is not typically formulated for prolonged exposure to solvents or heavy abrasion.

Key specifications

• Tip size: 0.4 mm (fine metal-clad tip)
• Ink type: permanent pigment ink (archival quality)
• Color: red
• Line characteristics: consistent, non-feathering, low bleed
• Barrel: lightweight cylindrical design with snap cap for secure storage

How to use

Uncap the pen and allow the tip a moment to start if it has not been used recently; then apply gentle, even pressure to produce a consistent 0.4 mm line. Use steady strokes for technical lines or controlled hatching for shading. When switching paper types, test on a corner to confirm bleed and drying behavior. Replace the cap after use to prevent the tip from drying out and store horizontally or capped in a pen case for best longevity.

What to consider before purchase

• Confirm the 0.4 mm tip size meets your required line width and detail level
• Check that the red pigment ink is suitable for your paper type to avoid unexpected bleed or show-through
• Consider whether archival, water-resistant pigment ink is necessary for your project

Usage recommendations

For best results, use the Sakura Pigma Micron 04 on quality drawing or drafting paper; test ink behavior on mixed-media sheets before applying to final artwork. Combine with pencils for preliminary sketches and allow ink to dry fully before erasing pencil marks or applying washes.
