posca uni PC-8K broad chisel paint markers — 8mm Grey 2-pack for opaque coverage & calligraphic lines

POSCA uni PC-8K is a water-based broad chisel paint marker (8mm) that delivers opaque, versatile coverage for large strokes, calligraphic curves and bold fills.

Designed for artists, crafters and makers who need a reliable, non-toxic paint marker for many surfaces, the PC-8K combines a removable chisel nib with vibrant, quick-drying ink. This grey 2-count set is ideal for outlining, filling large areas or creating graphic lettering on everything from skateboards and wood to glass and ceramics. The water-based formulation blends and dilutes easily for mixed-media effects, while remaining permanent on porous surfaces and removable on most smooth, non-porous materials.

How does the broad 8mm chisel tip change my workflow?

The 8mm chisel gives you two working edges in one tool: a wide flat face for full coverage and a thin edge for controlled strokes and calligraphy-like lines. It speeds up filling large shapes and produces clean contours for bold lettering.

• Chisel tip offers broad fills and precise angled lines
• 8mm width covers more area with fewer passes
• Removable nib can be washed to maintain flow
• Suitable for fast projects and detailed graphic work

What surfaces will the POSCA PC-8K work on?

POSCA markers perform well on over 50 materials, making them a go-to for multi-surface projects. The ink adheres permanently on porous substrates and wipes from many non-porous surfaces when desired.

• Porous: wood, paper, canvas — permanent once dried
• Non-porous: glass, metal, plastic — often erasable or removable
• Also compatible with leather, ceramic and painted surfaces
• Good for indoor and outdoor use when sealed appropriately

Can I mix or alter the colour and is it safe to use in studios?

The water-based ink blends, dilutes and layers easily, so you can create gradients, washes and mixed-media textures without harsh solvents. POSCA’s non-toxic formula makes it studio-friendly for adults and teens (not intended for children under 12).

• Mix colours wet-on-wet or layer after drying for depth
• Ink dilutes with water for wash effects and subtle shading
• Quick-drying to reduce smudging during layering
• Non-toxic composition but not marketed for small children
