posca uni PC-8K Water-Based Paint Markers — 8mm Chisel Tip, Green 2-Pack, Opaque & Washable

posca uni PC-8K is a water-based, 8mm chisel-tip paint marker designed to deliver opaque, broad coverage and crisp curved strokes for indoor and outdoor creative projects.

These green POSCA markers come as a two-pack and combine a removable, washable chisel nib with vibrant, water-based pigment that adheres permanently to porous surfaces and wipes clean from many smooth materials. The PC-8K is made for artists, crafters and decorators who need a single tool that can both fill large areas and produce graphic, calligraphic curves. Non-toxic and available in many colours, this model blends, layers and mixes with other POSCA inks for varied effects without harsh solvents.

How does the 8mm chisel tip balance precision and coverage?

The broad chisel tip of the PC-8K gives you two useful edges: a wide flat face for filling and a thin edge for stylized lines and curves. That dual action makes it easy to switch between bold colour blocks and more controlled strokes without changing tools.

• 8mm chisel for broad fills and tapered strokes
• Edge produces clean curve and calligraphy-like lines
• Single marker handles both detail and coverage tasks

Which surfaces and situations is this marker suitable for?

These water-based paint markers work on an extensive range of materials including wood, glass, metal, plastic, ceramic and fabric. The ink sets permanently on porous substrates, while on many non-porous surfaces it can be removed or wiped off before fully cured, making it versatile for craft, signage and décor.

• Effective on over 50 surfaces such as wood, leather, and metal
• Permanent on porous materials; erasable on many smooth surfaces
• Quick-drying for indoor and outdoor use

Can I blend or maintain the nib for long-term use?

Yes—POSCA paint is blendable and the PC-8K’s nib is both removable and washable, allowing you to control texture and colour mixing while prolonging the marker’s lifespan. Cleaning the nib helps preserve its shape for consistent strokes and makes colour changes easier when working with multiple hues.

• Nib can be removed and rinsed to restore flow and shape
• Paint blends and layers for gradients and mixed media effects
• Non-toxic formulation for safe studio handling (not for children under 12)

Who is this for? The POSCA uni PC-8K is ideal for illustrators, muralists, skateboard artists, hobbyists and decorators who need a dependable broad-tip marker with strong coverage and a calligraphic edge. Choose this two-pack if you want bold green accents, reliable indoor/outdoor performance and the flexibility to fill large areas while keeping control of line quality. Not intended for children under 12 years old.
