POSCA Pigment Marker PC-1MC, soft colors, 0.7–1.0 mm tip, waterproof, lightfast – single marker

POSCA Pigment Marker PC-1MC in soft colors is a single fine-to-medium tip marker designed for precise drawing and detailing. The round 0.7–1.0 mm tip delivers controlled lines and even coverage for outlines, handwriting and small filled areas. The pigment-based, alcohol-free ink is formulated to be waterproof and lightfast, giving durable, fade-resistant results on paper, card and a range of other surfaces used in illustration and mixed-media projects.

Advantages

This POSCA marker combines a compact 0.7–1.0 mm round nib with pigment ink that resists water and fading, making it suitable for archival sketches and work that will be handled or exposed to light. The alcohol-free formula minimises bleed-through on many papers and integrates well with other water-based media. The soft color palette provides muted tones for subtle detailing, layering and color accents without overpowering surrounding work.

Suitable for

• Precise drawing and illustration outlines
• Detailing and small areas in mixed-media artwork
• Lettering, annotations and bullet journaling
• Sketches, studies and on-the-go marking

When it may not be suitable

The PC-1MC's 0.7–1.0 mm round tip is intended for fine to medium detail work and small fills; it is not ideal for broad coverage or large background areas where wider nibs are more efficient. Although the ink is waterproof and lightfast once dry, it is pigment-based and may require multiple passes for fully opaque coverage on dark or highly textured surfaces.

Key specifications

• Tip type: round nib
• Tip size: 0.7–1.0 mm
• Ink type: pigment-based, alcohol-free
• Finish: opaque, waterproof when dry
• Colour family: soft/muted tones
• Suitable surfaces: paper, card and many mixed-media supports

How to use

Shake the marker well before use to mix the pigment. Press the nib gently on a scrap surface to activate ink flow and achieve the desired line intensity. Use light pressure for thin lines and slightly more pressure for broader strokes within the nib's range. Allow ink to dry fully to ensure waterproof and lightfast properties. Combine with other POSCA markers or water-based media for layering; avoid aggressive solvents that are not compatible with pigment inks.

What to consider before purchase

• If you need broad coverage or bold fills, consider larger-tip POSCA markers.
• Check that the soft color you choose provides the contrast required for your project.
• Ensure the chosen surface accepts pigment ink; very glossy non-porous surfaces may require primer or specific POSCA product types.

Usage recommendations

For consistent results, store the marker horizontally when not in use, prime the nib on scrap paper before each session, and layer light colors first. For archival projects, allow each layer to dry completely before overpainting to preserve opacity and waterproofing.
