Fineliner pen Sakura XSDK0149 black 0.25 mm tip, permanent pigment ink, ivory barrel

Sakura XSDK0149 fineliner pen features a 0.25 mm tip and permanent pigment ink in black, housed in an ivory-coloured barrel. Designed for precise, consistent lines, this single-piece fineliner is intended for tasks that require accuracy and archival-quality ink. The pigment formulation resists fading and water exposure, making it suitable for technical drawing, detailed illustration, note-taking, and document annotation where longevity and clarity are important.

Advantages

The 0.25 mm tip provides very fine, controlled strokes for detailed work, while the permanent pigment ink ensures water resistance and fade resistance for long-lasting marks. The ivory barrel gives a neutral visual appearance and comfortable handling for extended use. The pen’s consistent ink flow minimises skipping, enabling neat work across a variety of surfaces commonly used for drafting and illustration.

Suitable for

• Technical drawing and drafting requiring fine line precision
• Detailed illustration, sketches and ink work
• Annotation and labelling on documents and archival records
• Note-taking where permanent, water-resistant ink is preferred

When it may not be suitable

This fineliner’s very fine 0.25 mm tip is not intended for broad coverage, shading large areas, or high-volume coloring tasks. Users who need bold, thick lines or variable line width for calligraphy or brush-like effects may find this pen too narrow for their needs. Surfaces that are highly textured or absorbent may reduce line crispness and ink permanence.

Key specifications

• Tip width: 0.25 mm (very fine)
• Ink type: permanent pigment ink, black
• Barrel colour: ivory
• Single unit supply: one pen per package
• Line behaviour: water-resistant and fade-resistant when dry

How to use

Uncap the pen and allow a short stroke on scrap paper if the nib has not been used recently. Use light, steady pressure to preserve the fine tip and produce consistent 0.25 mm lines. For technical drawing, hold the pen at a shallow angle and move it smoothly along rulers or guides. After use, replace the cap to prevent the tip from drying. Store horizontally or tip-up to help maintain even ink flow when not in regular use.

What to consider before purchase

• Required line width: 0.25 mm is very fine and best for detailed work
• Surface type: smoother paper yields the cleanest lines; textured papers may affect results
• Need for permanence: pigment ink is water- and fade-resistant when dry
• Quantity: sold as a single piece—consider buying multiples for frequent use

Usage recommendations

For optimal results, pair the fineliner with smooth, high-quality drawing or archival paper and use a ruler for straight technical lines. Allow ink to dry fully before layering other media or handling documents to maintain water-resistance and archival quality.
