Uni POSCA PC-17K water-based pigment ink marker. Writes on virtually any surface with no bleed through on paper. Acrylic chisel-shaped nib writes a 15mm line.

POSCA works on most surfaces and is permanent on absorbent media such as paper and card, and can be removed from shiny surfaces with a scraper. To make permanent:

• Paper/Card: No action needed - POSCA pigment will be absorbed into the fibres, making it permanent.
• Terracotta: Bake in the oven at 220°C for 45 minutes, then spray with clear varnish.

• Metal: Spray with clear varnish.
• Glass: Bake in oven at 160°C for 45 minutes, then spray with clear varnish.
