posca PC-8K Water-Based Paint Markers — 8mm Chisel, Beige, 2-Count, Opaque Quick-Dry Coverage

The posca uni PC-8K is a water-based, broad 8mm chisel-tipped paint marker in beige, sold as a 2-count pack for versatile, opaque coverage on over 50 surfaces.

These POSCA PC-8K markers combine a wide chisel tip with water-based, opaque pigment designed to cover large areas and create clean, graphic curves. The ink dries quickly, works on porous and non-porous surfaces, and is removable from many smooth materials while remaining permanent on porous substrates. This pack of two beige markers is ideal when you need consistent colour for decorating, signage, or craft projects.

How does the PC-8K perform on different surfaces?

The PC-8K was formulated to adhere to a broad range of materials: wood, glass, metal, plastic, ceramic, leather and more accept the ink with good opacity. On porous surfaces like untreated wood or fabric, the pigment bonds and becomes long-lasting; on smooth materials such as glass or glazed ceramic, the mark can often be removed with rubbing if desired.

• Permanent on porous surfaces — excellent for furniture and unfinished wood
• Often erasable on many smooth non-porous surfaces like glass and metal
• Useful for indoor and outdoor projects thanks to quick-drying ink
• Works on over 50 materials for broad creative use

What kinds of marks and effects can I make with the 8mm chisel tip?

The 8mm chisel tip on the PC-8K gives you both bold fills and controlled line work; flip the marker to use the broad side for coverage or the edge for a crisp, calligraphy-style curve. The tip can be removed and washed, which lets you maintain a clean edge and extend the marker’s usable life.

• Wide strokes for filling backgrounds and large shapes
• Edge strokes for precise, calligraphic lines and curves
• Removable, washable nib supports cleaning and tip replacement
• Blendable, water-based pigments enable simple mixing and soft transitions

Is the ink safe and suitable for everyday creative use?

POSCA markers use water-based, non-toxic pigment ink, making them a popular choice for hobbyists, artists, and decorators. They are not designed or intended for children under 12; always supervise younger users and test on a small area first when working on delicate surfaces.

• Water-based and non-toxic formulation for safer studio use
• Quick-drying to reduce smudging during projects
• Available in 35 bright, opaque colours for coordinated palettes
• Not recommended for children under 12 — supervise use

How should I use and care for my POSCA PC-8K markers?

Shake the marker well before use to mix pigment and water base, then press the tip down gently until the ink flows. Store markers horizontally for even ink distribution, and wash the chisel nib if you plan to swap colours or preserve a sharp edge.

• Shake thoroughly and prime by pressing the tip to release ink
• Store horizontally to keep the chisel tip evenly saturated
• Remove and rinse the nib under water to clean or restore function
• Test on scrap material to gauge opacity and drying time before final application

Who is this for? The posca uni PC-8K 8mm Beige 2-pack suits artists, sign-makers, crafters, and decorators who need a reliable, opaque marker for large areas and bold lines. It’s a practical choice for customizing skateboards, adding lettering to windows, accenting furniture, or creating murals—any project that benefits from strong coverage, quick drying, and a washable chisel tip.
