POSCA PC-8K - Broad Chisel Tip

The POSCA PC-8K is POSCA's broad chisel tip marker — a bold, expressive tool designed for large-scale work, flat colour fills, street art, and graphic lettering. Its 8mm chisel tip gives you two line widths in one: use the edge for clean, precise strokes and calligraphic curves, or the flat face for wide coverage and bold fills.

Like all POSCA markers, it uses opaque, water-based pigment ink that is fade-proof and water-resistant once dry. Permanent on absorbent surfaces, and erasable on most smooth non-porous materials before sealing.
