posca PC-8K Water-Based Paint Markers, 8mm Chisel Tip — Red 2-Pack, Opaque Quick-Dry Coverage

POSCA uni PC-8K is a pair of water-based, broad 8mm chisel-tip paint markers in red designed to deliver opaque, glossy coverage and calligraphic lines on over 50 surfaces.

Whether you’re customizing a skateboard, adding lettering to a window, or touching up furniture, these POSCA PC-8K markers combine a wide chisel tip with water-based pigment for vivid, quick-drying colour. The non-toxic formula produces permanent results on porous materials and can be wiped from many smooth, non-porous surfaces, giving you flexibility for both temporary and lasting work. Each marker’s nib can be removed and cleaned, and the ink blends well with other colours for layered or mixed effects.

How will the 8mm chisel tip change my lettering and coverage?

The broad chisel shape lets you switch between thick, solid fills and crisp, slanted strokes without changing tools. That dual action is ideal for bold signage, graphic calligraphy, and filling large areas quickly while still achieving edge definition.

• Produces thick fills and sharp slanted lines with one tip
• Fills wide areas faster than fine-point markers
• Gives consistent ink flow for uniform coverage
• Chisel edge supports stylized lettering and graphic accents

Which surfaces work best with POSCA PC-8K markers?

These water-based markers are formulated to adhere to a broad range of materials, so you can use them on craft, home, and street-art projects alike. They perform well indoors and out, though permanence varies with the surface type.

• Permanent on porous substrates like wood, paper, canvas, and fabric
• Removable or erasable on many non-porous surfaces such as glass and glazed ceramic
• Works on metal, plastic, leather and painted surfaces when allowed to cure
• Suitable for both professional and hobbyist applications

How can I blend, layer, or maintain the markers for best results?

The water-based ink accepts dilution and blending, which lets you create gradients or custom shades by overlapping strokes while the paint is still wet. The nib is removable and washable, making maintenance and colour changes simple.

• Blend wet strokes for subtle fades or mix on a palette for custom hues
• Remove and rinse the tip to clear blockages or switch colours
• Allow layers to dry between coats for crisp edges and opacity control
• Store horizontally to keep ink flow consistent across markers

It’s especially useful for people creating large-scale lettering, high-contrast accents, or fast coverage across diverse materials.
