Fineliner pen Sakura Pigma Micron 01 — 0.25 mm, permanent pigment ink, purple

The Sakura Pigma Micron 01 fineliner with a 0.25 mm nib provides precise, consistent lines in purple pigment ink. Designed for drawing, technical sketches, illustration and detailed note-taking, the pen uses permanent pigment ink that is water- and fade-resistant, making it suitable for archival work and mixed-media projects. The slim nib produces an even, controlled line ideal for fine hatching, lettering and intricate detail work.

Advantages

The Micron 01 offers a very fine 0.25 mm line width that maintains consistent ink flow without blotting or skipping. The pigment-based ink is permanent and resistant to water and fading, supporting long-term durability of drawings and documents. The pen’s lightweight barrel and precise tip enhance control for detailed work, and the purple color expands creative and organizational options compared with standard black or blue pens.

Suitable for

• Technical drawing and architectural sketches requiring fine detail
• Illustration, inking and pen-and-ink techniques
• Note-taking, annotating and color-coded journaling
• Mixed-media artwork where water-resistant pigment ink is needed
• Archival documents, scrapbooking and long-term records

When it may not be suitable

The very fine 0.25 mm nib is not ideal for covering large areas quickly or for bold strokes; broader nibs or brush pens are better suited to those tasks. Because the ink is pigment-based and permanent, it may show through very thin paper or feather on low-quality, highly absorbent paper, so testing on a small area is recommended for unfamiliar substrates.

Key specifications

• Line width: approximately 0.25 mm
• Tip type: rigid fineliner nib designed for precise lines
• Ink type: permanent pigment ink, water-resistant and fade-resistant
• Ink color: purple
• Form factor: single fineliner pen with lightweight barrel for control

How to use

Shake not required; uncapped, hold the pen at a comfortable angle and apply gentle consistent pressure for an even 0.25 mm line. Use short, controlled strokes for fine hatching or detailed work and longer smooth movements for continuous lines. Allow ink to dry before layering water-based media or applying additional ink to avoid smudging; when combining with watercolors, the pigment ink will remain stable and resist running.

What to consider before purchase

• Desired line width: 0.25 mm is suited for fine detail, not broad coverage
• Paper quality: use medium to heavy-weight, smooth paper to minimise show-through and feathering
• Ink permanence: pigment ink is permanent and water-resistant—suitable for archival use
• Color choice: purple provides an alternative to black/blue for creative or organizational uses

Usage recommendations

For best results, pair the fineliner with smooth, heavyweight paper (e.g., 90–200 gsm) and allow ink to dry fully before erasing pencil guides or applying additional media. Use the 0.25 mm tip for detail work, technical lines and lettering; switch to broader tips for shading or bold lines.
