POSCA Pigment Marker PC-5BR Brush, black, semi-flexible foam tip, stroke 1.0–4 mm, 1 pc (PC5BR N)

The POSCA Pigment Marker PC-5BR Brush in black is a water-based pigment ink marker featuring a semi-flexible foam brush tip that produces variable strokes from 1.0 to 4 mm. Opaque pigment ink ensures consistent, lightfast coverage across paper, cardboard, wood, metal and many other surfaces. The brush-shaped tip provides control for both fine lines and broader strokes, making the marker suitable for illustration, hand-lettering, outlining and detailed work where smooth ink flow and variable line width are needed.

Advantages

This marker combines a brush-like semi-flexible foam tip with opaque water-based pigment ink to deliver smooth, even coverage and reliable colour saturation. The formulation is water-based and low-odor while remaining resistant to fading, providing durable results on porous and non-porous surfaces. The tip’s spring and flexibility allow for controlled line variation from thin to medium-thick strokes without interrupting ink flow.

Suitable for

• Illustrations and sketching where variable line width is required
• Hand-lettering, calligraphy and sign writing
• Outlining, detailing and filling small to medium areas
• Working on paper, cardboard, wood, metal and prepared plastics

When it may not be suitable

The marker is not intended for precise technical drafting that requires mechanically consistent line widths under 1.0 mm; very fine technical lines are better achieved with fine nib or technical pens. Although the ink adheres to many surfaces, adhesion and longevity on some non-porous materials and glossy finishes may require surface preparation or a compatible primer or sealer.

Key specifications

• Tip type: brush-shaped semi-flexible foam
• Stroke width: variable, approximately 1.0–4 mm
• Ink: opaque, water-based pigment
• Colour: black
• Suitable surfaces: paper, cardboard, wood, metal, prepared plastics and similar materials

How to use

Shake the marker well with the cap on to mix the pigment. Press the tip gently on scrap material several times until the ink flows evenly. Use light pressure for thin lines and increase pressure or change the angle of the tip for broader strokes. For best results on non-porous or glossy surfaces, test on a small area first and consider using a primer or surface preparation. Cap the marker after use to prevent the tip from drying out.

What to consider before purchase

• Intended line width: variable between 1.0 and 4 mm — not suited for ultra-fine technical lines
• Surface compatibility: performs best on porous or properly prepared non-porous surfaces
• Ink type: water-based pigment — opaque and lightfast but may need sealing for outdoor exposure
• Tip flexibility: semi-flexible foam offers brush effects but will wear with heavy abrasion

Usage recommendations

For consistent performance, store the marker horizontally and recap immediately after use. When switching between detailed work and broader fills, adjust pressure and angle rather than switching tools; the semi-flexible brush tip is designed to produce smooth transitions between thin and thicker strokes.
