Uni-Ball Posca PC-17K Paint Marker Black — 2-Pack Jumbo Extra-Broad Tip, Opaque Coverage

The Uni Posca PC-17K Black is a jumbo, water-based paint marker that delivers rich, opaque black coverage across paper, wood, metal, glass and more.

Imported from Japan in Komainu-Dou original packaging, this two-pen pack of Posca PC-17K markers is built for bold marks, rapid coverage and reliable colour payoff. The PC-17K is designed for artists, sign makers and crafters who need a high-opacity, quick-drying paint pen that resists smudging once dry and layers cleanly without solvent odours.

How does the PC-17K perform on different surfaces?

The PC-17K uses a water-based pigment ink formulated to stick to porous and non-porous surfaces alike. It lays down dense, matt black colour in one or two passes and adheres to paper, cardboard, wood, canvas, metal, ceramic and glass for long-lasting marks.

• Strong opacity for one-pass coverage on dark and light backgrounds
• Works on smooth and textured surfaces without feathering
• Dries to a matte finish and resists light smudging when set

What kind of tip does this marker have and what line widths can I expect?

The PC-17K features a generous, durable tip designed for broad strokes, filling shapes and bold lettering. It produces wide, consistent lines that make it ideal for posters, murals, packaging design mockups and any work that benefits from large, visible marks.

• Extra-broad tip for thick, uniform coverage
• Tip retains shape under moderate pressure for consistent marks
• Good for lettering, backgrounds and quick area fill

How should I use and care for these markers to get the best results?

Shake the marker vigorously before use and prime the tip by pressing it down until paint flows evenly. Cap the pens after use to prevent drying, store horizontally for balanced ink distribution, and clean the tip with a damp cloth if residue builds up.

• Shake well and prime tip before first use
• Cap tightly and store horizontally between sessions
• Wipe tip gently to clear clogs and maintain flow

Are these pens safe for studio and classroom use?

The PC-17K uses water-based pigment ink with minimal odour compared with solvent markers, making it suitable for indoor creative environments. While it is not edible and should be kept away from children under supervision, it offers a lower-odour option for shared spaces.

• Water-based formulation with low odour compared to solvents
• Easy cleanup from hands and many surfaces while wet
• Not intended for food-contact items or body painting

Who is this for? The Uni Posca PC-17K Black two-pack is for artists, designers, muralists, sign painters and hobbyists who need bold, dependable black coverage in a jumbo, easy-to-use pen. Choose this kit if you want a Japanese-imported Posca marker that fills large areas quickly, produces consistent, matte results, and pairs well with finer Posca tips for mixed-width projects.
