Marker POSCA PC-5M by POSCA — pigment marker, round tip, stroke 1.8–2.5 mm, color: dark brown (PC5M MF)

POSCA PC-5M is a single-piece pigment marker with a round tip that produces consistent medium-thick lines with a stroke width of 1.8–2.5 mm. The ink is opaque, water-based pigment formulation in dark brown, designed to deliver lightfast and bleed-resistant coverage on paper, cardboard, wood, fabric and many other porous and semi-porous surfaces. The pen is intended for illustration, lettering, decorating and a wide range of craft applications where precise, uniform strokes and durable colour are required.

Advantages

The marker uses a pigment-based, water-soluble ink that provides dense, non-transparent colour and dries to a matte finish. Its single-piece design and round medium tip ensure stable, controllable lines from 1.8 to 2.5 mm without frequent pressure adjustment. Dark brown pigment offers good contrast on light backgrounds and remains resistant to bleeding and feathering on common art and craft substrates. The refillable-feel body and durable tip make it suitable for repeated use in projects requiring consistent results.

Suitable for

• Illustration and sketching with medium-thick outlines
• Hand lettering and calligraphy with a uniform round stroke
• Decorating paper, cardboard and wood surfaces
• Mixed-media artworks where water-based pigment is preferred
• Craft projects on fabric and textile accents (test first on scrap)

When it may not be suitable

This marker is not intended for high-precision technical drawing that requires very fine lines thinner than 1.8 mm, nor is it formulated as a permanent solvent-based marker for non-porous materials like glass or glazed ceramics without additional sealing. On very dark or highly glossy surfaces the dark brown pigment may show reduced contrast or limited adhesion unless the surface is prepared properly.

Key specifications

• Tip type: round tip
• Stroke width: 1.8–2.5 mm
• Ink type: water-based pigment
• Finish: opaque, matte
• Suitable surfaces: paper, cardboard, wood, fabric and many porous/semi-porous substrates
• Colour: dark brown

How to use

Shake the marker well with the cap on before use to mix the pigment evenly. Press the tip gently on a protected surface to prime the ink until the desired flow is achieved. Draw with a steady hand, holding the marker at a comfortable angle to produce uniform lines in the 1.8–2.5 mm range. Allow the ink to dry fully between layers; for fabric applications follow up with heat-setting or a fixative as recommended for the textile project. Recap the pen after use to preserve tip condition and prevent drying.

What to consider before purchase

• Intended line thickness (medium round 1.8–2.5 mm)
• Compatibility with your primary surfaces (porous or semi-porous recommended)
• Colour choice: dark brown may be less visible on dark backgrounds
• Not a solvent-based permanent marker for smooth non-porous surfaces

Usage recommendations

For best results, test the marker on a scrap piece of the target material to check adhesion, opacity and drying time. Use multiple light passes for fuller coverage rather than heavy single strokes to reduce tip wear and prevent pooling. When working on fabric, consider heat-setting or using a textile medium to improve washfastness.
