POSCA Pigment Marker PC-5BR Brush, grey ink, semi-flexible foam tip, stroke 1.0–4 mm, single unit

POSCA Pigment Marker PC-5BR Brush with grey ink is a single-unit, refillable pigment marker featuring a semi-flexible foam brush tip that delivers a variable stroke width from 1.0 to 4 mm. Designed for artists, illustrators and craft professionals, this marker lays down opaque, water-based pigment on a wide range of surfaces including paper, cardboard, wood, metal and ceramics. The grey tone is lightfast for consistent color across projects and the brush-like tip enables both fine lines and broader strokes in one tool.

Advantages

The semi-flexible foam brush tip combines control and versatility, allowing smooth transitions between delicate outlines and broader fills without changing tools. Water-based pigment ink provides strong opacity and matte finish, dries quickly and is suitable for layering. Refillable construction reduces waste and ensures long-term use, while the grey pigment maintains color stability and resists fading under normal indoor conditions.

Suitable for

• Illustration and sketching that require variable line widths
• Signage and lettering work on paper, cardboard and wood
• Mixed-media and craft projects on metal and ceramic surfaces
• Detailing and shading where controlled brush strokes are needed

When it may not be suitable

This marker is not formulated as an industrial coating and is not intended for long-term outdoor exposure without protective varnish; extended UV exposure may gradually affect pigments. It may not perform as well on highly glossy, non-porous plastics unless the surface is prepared or sealed first, and extremely fine technical drafting narrower than 1.0 mm will exceed the tip's minimum stroke width.

Key specifications

• Ink type: water-based pigment
• Tip type: semi-flexible foam brush
• Stroke width: adjustable 1.0–4 mm
• Color: grey, lightfast pigment
• Suitable surfaces: paper, cardboard, wood, metal, ceramics
• Finish: opaque, matte
• Refillable: yes

How to use

Shake the marker before use to mix the pigment evenly, then press the tip gently on scrap paper until ink flows. Vary angle and pressure to achieve strokes between 1.0 and 4 mm; use the tip flat for broader fills and on-edge for finer lines. Allow each layer to dry before applying additional pigment to avoid smudging. For non-porous surfaces, test adhesion on a small area and consider using a primer or sealant for best durability.

What to consider before purchase

• Intended surface types—best results on porous and lightly primed materials
• Required stroke range—1.0–4 mm suits versatile brush-style work but not ultra-fine technical lines
• Lightfastness and indoor vs. outdoor use—protect outdoor pieces with varnish
• Refill option and tip replacement availability for long-term projects

Usage recommendations

For consistent results, store horizontally when not in use, prime the tip on scrap material before the first application, and allow painted surfaces to cure before applying a clear protective finish when needed. Use moderate pressure to preserve the semi-flexible foam tip and clean non-porous surfaces before application to improve adhesion.
