posca uni PC-8K Water-Based Paint Markers — Metallic Violet 2-Pack, 8mm Chisel Tip, Opaque Quick-Dry

Posca uni PC-8K Metallic Violet is a pair of water-based, 8mm chisel-tip paint markers made for bold coverage, smooth calligraphic strokes, and versatile indoor/outdoor decoration.

These POSCA PC-8K markers combine opaque, water-based pigment with an 8mm broad chisel nib so you can switch quickly between wide fills and crisp angled strokes. The metallic violet finish stands out on dark and light surfaces alike, while the washable removable nib and quick-drying ink make the pens easy to maintain during creative sessions. They work on more than 50 surfaces, from wood and fabric to metal and glass, and are offered in a wide palette for layered, blended or single-pass colour work.

How does the 8mm chisel tip perform for different techniques?

The broad chisel tip is shaped to deliver both thick colour fills and controlled edge lines. Turn the marker on its side for broad coverage, or use the beveled edge for hairline and calligraphy-style strokes. The tip is removable and washable, letting you preserve flow and shape over repeated use.

• 8mm chisel for wide fills and sharp angled lines
• Switch between edge and flat surfaces for varied stroke widths
• Removable, washable nib extends marker life and consistency
• Quick-dry formulation reduces smudging on most surfaces

Which surfaces take metallic violet best and is it permanent?

POSCA ink is highly opaque and bonds permanently to porous materials like paper, wood and untreated fabric; on non-porous surfaces such as glass or glazed ceramic it can be removed if needed. The metallic pigment holds visual impact on dark backgrounds and reflects light for a shimmering finish.

• Permanence on porous surfaces: paper, raw wood, cardboard
• Removable or erasable on many smooth non-porous surfaces
• Works on glass, metal, plastic, leather, ceramic with vivid coverage
• Ideal for contrasting metallic effects on dark or light bases

Can these markers be blended, layered or watered down?

Yes — the water-based pigment is mixable and can be diluted for wash effects, or layered after drying for richer depth. While designed as an opaque single-pass marker, you can overlap colours, feather edges, or use a damp brush to soften transitions.

• Dilute with water for transparent wash techniques
• Layer once the first coat dries for deeper tones and highlights
• Blend adjacent strokes with a wet brush for smooth gradients
• Test on a scrap surface to control dilution and drying time

How should I care for and store these pens to keep them working?

Proper care keeps the chisel tip responsive and the flow steady: recap after use, clean the tip when colour build-up appears, and store horizontally to keep the pigment evenly distributed. If the nib becomes clogged, remove and rinse it under water until the pigment clears, then let it dry before reattaching.

• Recap immediately to prevent drying
• Store horizontally to balance pigment and prevent pooling
• Rinse removable nibs under water if they clog; air-dry fully
• Shake gently before priming to reactivate pigment flow

Who is this for? Artists, muralists, crafters and decorators who need bold, opaque metallic colour and the flexibility to switch between sweeping fills and precise, calligraphic strokes will appreciate the POSCA uni PC-8K 8mm markers. They suit hobbyists customizing skateboards or helmets, designers adding accents to furniture, and signmakers or window decorators working indoors or outdoors.
