Marker uni mitsubishi pencil POSCA PC-17K black — 15 mm tip, poster paint marker

POSCA PC-17K by uni mitsubishi pencil is a black poster paint marker with a 15 mm bullet/chisel-style tip that produces bold, opaque lines. The water-based pigment ink provides strong coverage on porous surfaces such as paper, cardboard, poster board and raw wood. The marker is designed for projects that require visible, matte black strokes and fast layering without feathering or heavy bleed-through when used on appropriate substrates.

Advantages

The large 15 mm tip combines chisel and bullet characteristics to allow both broad strokes and controlled edging. Water-based pigment ink offers good opacity, quick drying and low odor compared with solvent-based alternatives. The ink is lightfast and lays down a matte finish that remains visible on coloured or textured surfaces. The marker’s robust tip resists deformation under moderate pressure and maintains consistent ink flow for uniform coverage.

Suitable for

• Signage and posters for indoor displays
• School and classroom projects on paper or cardboard
• Art and craft projects on wood, poster board and canvas board
• Packaging and mock-ups requiring bold black markings

Key specifications

• Tip shape and size: 15 mm bullet/chisel-style tip for broad and edged strokes
• Ink type: water-based pigment ink with opaque coverage
• Finish: matte, opaque black
• Suitable surfaces: paper, cardboard, poster board, raw wood and other porous materials
• Drying: fast-drying for quick layering and reduced smudging

How to use

Shake the marker vigorously with the cap on to mix the pigment and carrier. Press the tip down repeatedly on a scrap surface until the ink flows evenly to the nib, then test on scrap material before applying to the final surface. Apply steady pressure for consistent broad strokes or angle the tip for narrower, controlled lines. Allow each layer to dry before overpainting to avoid unwanted smearing. Store horizontally when not in use to preserve tip saturation.

Usage recommendations

For best results on porous surfaces, prime very absorbent substrates with a light ground or gesso to reduce excessive absorption. When working on non-porous surfaces, use a suitable primer or test adhesion first. Cap the marker securely after use and store at room temperature away from direct sunlight to extend ink life.
