Marker POSCA PC-5BR Brush by POSCA — pigment marker, half-flexible foam brush tip, stroke 1.0–4 mm

POSCA PC-5BR Brush is a pigment marker featuring a half-flexible foam brush tip that provides a variable stroke width from 1.0 to 4 mm. The marker uses opaque, water-based pigment ink that adheres well to paper, cardboard and canvas as well as many other porous surfaces used in drawing, lettering and mixed-media work. Its brush-like tip combines the control of a marker with the expressive line variation of a brush, making it suitable for detailed illustrations and broader strokes.

Advantages

The POSCA PC-5BR delivers consistent, lightfast pigment coverage with a matte finish and strong opacity, allowing for layering and highlights on colored or dark backgrounds. The half-flexible foam brush tip adapts to pressure to create thin hairlines and wider swashes without the need to change tools. Being water-based and pigment-based, the ink is low-odor, cleans easily from non-porous surfaces while staying permanent on porous substrates after drying.

Suitable for

• Hand lettering and calligraphy with variable stroke width
• Illustrations and sketching requiring both fine lines and broader strokes
• Mixed-media art on paper, cardboard and canvas
• Detail work and highlights on colored or dark surfaces
• Hobby and craft projects that need opaque, water-based pigment ink

When it may not be suitable

The PC-5BR is optimized for porous surfaces; on many non-porous substrates such as untreated plastics, metals or glass the ink may not adhere permanently without prior surface preparation. While water-resistant once dry on porous materials, the marker is not recommended where high abrasion resistance or outdoor permanence without sealing is required.

Key specifications

• Tip type: half-flexible foam brush tip
• Stroke width: variable, approximately 1.0–4 mm
• Ink type: water-based pigment ink
• Finish: opaque, matte coverage
• Suitable surfaces: paper, cardboard, canvas and other porous substrates

How to use

Shake the marker well with the cap on to mix the pigment. Press the tip lightly on a scrap surface to prime the ink until flow begins. Use varied pressure and angle to control line width; hold the marker upright for finer lines and flatter for broader strokes. Allow the ink to dry thoroughly on porous surfaces; for multi-layer work wait until the previous layer is dry before applying the next. Clean excess ink from the tip by drawing on scrap paper; replace the cap after use to prevent drying.

What to consider before purchase

• Intended surface: best results on porous materials such as paper, cardboard and canvas
• Desired stroke variability: tip supports 1.0–4 mm range through pressure and angle
• Finish and opacity needs: opaque, matte pigment ink suitable for layering
• Durability expectations: water-resistant on porous surfaces after drying but may require sealing for outdoor or high-abrasion use

Usage recommendations

For consistent results, test the marker on a similar scrap surface before working on the final piece, control stroke width by adjusting pressure and angle, and seal finished outdoor or heavily handled projects with an appropriate fixative if long-term durability is required.
