Marker POSCA PC-5M by POSCA, pigment marker, round tip, chestnut (PC5M CHT), stroke 1.8–2.5 mm

POSCA PC-5M by POSCA is a single-pigment pigment marker with a durable round tip that produces a consistent 1.8–2.5 mm stroke. The water-based, opaque pigment ink provides even, fade-resistant coverage on porous and non-porous surfaces including paper, cardboard, wood, metal and glass. The chestnut shade offers a warm, medium-dark brown ideal for illustration details, hand-lettering accents and craft work where precise medium-width lines are required.

Advantages

The marker delivers uniform pigment flow and quick, opaque coverage that adheres well to multiple surfaces without solvent odor. Its round tip retains shape under typical artistic use and allows controlled strokes between 1.8 and 2.5 mm. Being water-based, the ink is easy to layer and clean from many non-porous surfaces while remaining lightfast and resistant to fading on properly prepared substrates.

Suitable for

• Illustration and sketching where medium-width lines and solid fills are needed
• Hand-lettering, calligraphy accents and outlining
• Craft projects on paper, cardboard, wood and ceramics
• Signage, labeling and mixed-media studio work

When it may not be suitable

This marker is not formulated for permanent outdoor exposure on unsealed surfaces; prolonged UV and weather exposure can affect longevity. It may not perform reliably on highly flexible plastics or very oily/greasy surfaces where adhesion is poor. For extremely fine detail below 1.8 mm or very broad coverage in a single pass, a finer or broader tip size may be more appropriate.

Key specifications

• Ink type: water-based opaque pigment
• Tip type: durable round tip
• Line width / stroke: 1.8–2.5 mm
• Colour family: chestnut (medium-dark brown)
• Suitable surfaces: paper, cardboard, wood, metal, glass and many other porous and non-porous materials
• Opacity: high, suitable for layering and covering darker backgrounds

How to use

Shake the marker well before use, holding the cap on while shaking to mix the pigment. Press the tip gently on a scrap surface to prime the ink flow until the pigment appears evenly. Draw with even pressure to achieve strokes between 1.8 and 2.5 mm; for darker or more opaque coverage, apply multiple layers allowing a short drying interval between passes. After use, replace the cap firmly to prevent the tip from drying out.

What to consider before purchase

• Desired line width: this model produces medium-width strokes (1.8–2.5 mm)
• Surface compatibility: performs best on clean, dry, non-greasy surfaces
• Colour choice: chestnut gives a warm brown tone—confirm it suits your palette
• Indoor vs outdoor use: for long-term outdoor exposure, consider sealing or using products specified for outdoor permanence

Usage recommendations

For best results on non-porous surfaces like glass or metal, test on a small area first and allow ink to dry fully; consider a clear sealer for added durability. Store capped horizontally or tip-up to maintain even ink distribution.
