Marker POSCA PC-5BR BRUSH, dark blue, semi-flexible foam brush tip, stroke 1.0–4 mm, single piece

POSCA PC-5BR BRUSH, dark blue, is a water-based pigment marker with a semi-flexible foam brush tip that produces strokes from approximately 1.0 to 4 mm. The opaque dark blue pigment ink offers consistent coverage on paper, cardboard and many other porous and non-porous surfaces. This single-piece marker is designed for drawing, lettering, illustration and mixed-media work where both fine lines and broader brush-like strokes are required.

Advantages

The semi-flexible foam brush tip adapts to pressure and angle, allowing variable stroke widths and smooth transitions between thin and broad marks. The water-based pigment ink dries to an opaque, matte finish, resists bleeding on most papers and layers well over light colours. The marker is refill-free and ready to use out of the box, offering reliable colour intensity and consistent flow for detailed work as well as expressive brush strokes.

Suitable for

• Hand lettering and calligraphy on paper and cardstock
• Illustration, sketching and outlining
• Mixed-media projects combining inks, paints and markers
• Signage and small craft projects on wood, fabric primed surfaces and cardboard

When it may not be suitable

This marker uses water-based pigment ink which performs best on prepared, absorbent or primed surfaces; on very smooth, glossy or oily surfaces adhesion and opacity may be reduced. It is not formulated as a permanent solvent marker for heavy outdoor exposure or applications requiring industrial-grade fastening to rough, unprimed materials.

Key specifications

• Tip type: semi-flexible foam brush
• Stroke width: approximately 1.0–4 mm depending on pressure and angle
• Ink type: water-based pigment, opaque matte finish
• Colour family: dark blue
• Suitable surfaces: paper, cardboard, primed wood, some fabrics and other mixed-media supports

How to use

Shake the marker gently before use to mix the pigment evenly. Press the tip down briefly on scrap paper to prime the ink flow if needed, then adjust pressure and angle to achieve the desired stroke width between 1.0 and 4 mm. Work in layers for deeper colour, allowing each layer to dry to avoid smudging. Clean the tip by writing on scrap paper if pigment buildup occurs. Store horizontally when not in use to maintain even ink distribution.

What to consider before purchase

• Check surface compatibility — test on a scrap piece if using non-paper substrates
• Consider stroke range (1.0–4 mm) to ensure it meets your line-width needs
• Water-based pigment ink is not intended for prolonged outdoor exposure without protection

Usage recommendations

For consistent results, prime the marker on scrap paper before applying to your final work. Use light pressure for fine lines and increase pressure or change angle for broader brush strokes. When combining with solvent-based media, allow the ink to dry fully and test adhesion first.
