Fineliner pen Sakura Pigma Micron 01 blue, tip 0.25 mm, permanent pigment ink

The Sakura Pigma Micron 01 fineliner in blue is a single-piece drafting pen with a 0.25 mm metal-tipped nib and pigment-based permanent ink. It is formulated for precise, consistent lines and is suited to technical drawing, illustration, sketching and archival note-keeping. The ink is designed to resist fading, water contact and smearing, making the pen appropriate for documents and artworks that require long-term legibility and clean line definition.

Advantages

The pen delivers clean, stable ink flow and a uniform 0.25 mm line width that supports fine detail work. Permanent pigment ink provides high resistance to water and fading, and it dries quickly to reduce smearing during use. The single-piece construction and firm metal tip offer reliable control for repetitive strokes and precise hatchwork, while the neutral blue tone is suitable for both artistic and professional contexts.

Suitable for

• Technical drawing and drafting where fine, consistent lines are required
• Illustration, inking and comic linework with detailed cross-hatching
• Fine handwriting and archival notes that need to remain legible over time
• Mixed-media artwork when using water-resistant ink over washes

When it may not be suitable

This fineliner is not intended for broad coverage, marker-style filling or calligraphy that requires flexible nibs; its fixed metal tip and 0.25 mm width limit how quickly large areas can be filled. Although the pigment ink is water-resistant when dry, it is not a substitute for specialized archival inks for high-end conservation projects requiring certification.

Key specifications

• Tip type: metal needlepoint
• Tip size: 0.25 mm (approx. 0.25 mm line)
• Ink type: pigment-based permanent ink
• Ink properties: water-resistant, fade-resistant, quick-drying, smear-resistant
• Color: blue
• Body: single-piece fineliner design

How to use

For best results, hold the pen at a steady angle and apply light, consistent pressure to maintain the fine 0.25 mm line width. Allow ink to dry fully before layering other media or handling the page. Use short, controlled strokes for technical lines and longer, continuous strokes for smooth outlines. Replace the cap after use to prevent drying and store horizontally or with the tip pointing upward for extended shelf life.

What to consider before purchase

• Desired line width: 0.25 mm is best for fine detail, not for filling large areas
• Need for water- and fade-resistance for archival or mixed-media work
• Compatibility with your paper type—very rough surfaces may wear the tip faster
• Single pen purchase versus multi-pen sets if you need multiple colors or widths

Usage recommendations

Use the Sakura Pigma Micron 01 blue for detailed technical sketches, inked illustrations and archival annotations. Pair with smooth, quality paper to preserve the crispness of the 0.25 mm lines and allow full drying before erasing pencil guides or applying washes.
