Marker POSCA PC-5BR Brush by POSCA, half-flexible foam tip, stroke 1.0–4 mm, assorted color set (8) — single piece

POSCA PC-5BR Brush is a water-based pigment marker with a half-flexible foam brush tip that produces strokes from 1.0 to 4 mm. Supplied here as an assorted 8-color set sold as a single piece, this marker provides opaque, lightfast pigment ink that adheres to porous and non-porous surfaces including paper, canvas, wood and ceramics. The reversible brush-style tip enables both fine lines and broader strokes, making it suitable for illustration, lettering and mixed-media craftwork.

Advantages

The half-flexible foam brush tip offers a controlled, consistent ink flow for variable stroke widths between 1.0 and 4 mm without the need to change tools. The water-based pigment formulation delivers vivid, opaque coverage with minimal bleed on most papers and good adhesion to prepared non-porous surfaces. Pigment-based ink increases light resistance and reduces fading in finished work compared with dye-based markers. The marker is packaged in an 8-color assorted set to provide a compact selection of commonly used hues for drawing and decorating.

Suitable for

• Illustration and sketching on paper and sketchbooks
• Hand lettering, calligraphy and sign-making
• Layered work and mixed-media art on canvas
• Decorating prepared wood, ceramics and craft objects
• School and hobby projects requiring opaque, water-based ink

When it may not be suitable

This marker may not be ideal for extremely detailed micro-line work where tips smaller than 1.0 mm are required. Because ink is water-based pigment, finished work intended for continuous outdoor exposure or heavy abrasion should be sealed with an appropriate varnish or fixative to protect against weathering and mechanical wear. Some very smooth, untreated non-porous surfaces may require surface preparation to improve adhesion.

Key specifications

• Tip type: half-flexible foam brush (reversible brush-style)
• Stroke width: 1.0–4 mm
• Ink type: opaque water-based pigment ink
• Color set: assorted 8 colors (single-piece offer)
• Suitable surfaces: paper, canvas, wood, ceramics, mixed media

How to use

Shake the marker well with the cap on to mix the pigment. Unlock the tip according to the manufacturer's activation instructions (typically pressing the tip to a protected surface until ink flows). Use the narrow edge of the brush tip for fine lines and the broad side for wider strokes; adjust pressure to vary line width between 1.0 and 4 mm. Allow layers to dry between applications when building opaque coverage or working in mixed media. For use on non-porous materials such as ceramics or sealed wood, test adhesion on a small area first and seal the finished piece if it will be handled frequently or exposed to moisture.

What to consider before purchase

• Verify that the included palette of 8 assorted colors fits your project needs.
• Consider whether a 1.0–4 mm stroke range matches the level of detail you require.
• Plan for sealing or varnishing if the artwork will face outdoor exposure or heavy handling.
• Check compatibility with the specific surface or base materials you intend to use.

Usage recommendations

For consistent results, store markers horizontally when not in use and recap immediately after use to prevent drying. When layering on paper or canvas, allow each layer to dry completely to avoid disturbing lower layers; for non-porous surfaces, consider a clear fixative or kiln/oven curing where appropriate and compatible with the substrate.
