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

The Sakura Pigma Micron 04 fineliner in blue features a 0.4 mm metal-clad tip and archival-quality permanent pigment ink. Designed for precise, consistent lines, this pen produces fade- and water-resistant marks that are suitable for drawing, illustration, technical sketches, and detailed note-taking. The compact, lightweight barrel supports extended use and accurate control for tasks that require fine line work.

Advantages

The pigment-based ink is permanent, quick-drying and resistant to water and fading, which preserves line clarity over time. The 0.4 mm tip delivers uniform, reliable strokes for fine details and consistent lettering. The pen’s construction provides steady ink flow and a comfortable grip for repetitive use, making it practical for professional and hobby applications.

Suitable for

• Technical drawing and architectural sketches
• Illustration, inking and comic art
• Bullet journaling, planners and precise handwriting
• Field notes, archival documentation and labelling
• Mixed-media work where water-resistant ink is required

When it may not be suitable

This fineliner is intended for precise line work rather than broad coverage; it is not designed for colouring large areas. Because the tip is fine, it may clog if used on very rough or fibrous surfaces. The permanent pigment ink is not formulated for use on non-porous surfaces like some plastics or glazed ceramics without prior testing.

Key specifications

• Tip size: 0.4 mm (fine)
• Ink type: Permanent pigment ink
• Colour: Blue
• Line quality: Consistent, quick-drying, water-resistant and fade-resistant
• Body: Slim, lightweight barrel designed for control

How to use

Shake is not necessary; remove the cap and begin drawing with light, steady pressure to maintain the 0.4 mm line width. For the longest life, store the pen capped and horizontally when not in use. If the pen is used on rough paper, allow ink to dry fully to avoid smudging. Test on a scrap of the intended surface when working on non-standard materials to confirm adhesion and permanence.

What to consider before purchase

• Choose the 0.4 mm tip when you need fine, precise lines rather than broad coverage.
• Confirm that blue pigment ink meets archival or documentation requirements for your project.
• Verify compatibility with the paper or surface texture to avoid clogging or feathering.

Usage recommendations

Use the Sakura Pigma Micron 04 for detailed inking, technical lines and archival notes; combine with wider-tip pens for outlining larger areas and with waterproof washes for mixed-media pieces where permanence is required.
