Marker POSCA uni PC-17K — Chisel tip, Blue, 15 mm line

The POSCA uni PC-17K is a water-based chisel-tip marker that delivers opaque, vibrant blue colour suitable for bold lines and broad coverage on multiple surfaces such as paper, plastic, glass and fabric. Supplied as a single marker, its large 15 mm chisel tip allows for both wide strokes and controlled angled edges, making it useful for signage, posters and artistic work that requires solid, uniform coverage.

Advantages

The marker uses water-based pigment ink that provides strong, opaque colour with a matte finish and good hiding power. Its chisel-shaped, wide tip offers versatile stroke widths from broad fills to angled lines, while the formulation adheres well to porous and non-porous surfaces including paper, plastic, glass and fabric. A single-piece supply makes it convenient to keep as a tool for large-scale artwork or bold graphic applications.

Suitable for

• Poster and sign making
• Large-area coverage and background fills
• Street art and illustration on mixed surfaces
• Decorating glassware, plastic items and textiles

When it may not be suitable

Because the tip is large and chisel-shaped, the marker is not ideal for fine detail work or extremely narrow lettering. Although the ink adheres to many surfaces, some smooth non-porous materials may require surface preparation or sealing for long-term durability, especially on items that will be washed or handled frequently.

Key specifications

• Ink type: water-based pigment
• Colour: blue
• Tip type and width: chisel tip, approximately 15 mm
• Suitable surfaces: paper, plastic, glass, fabric
• Finish: opaque, matte coverage

How to use

Shake the marker well with the cap on to mix the pigment. Press the tip gently on scrap material to prime the flow until the ink reaches the nib. Use the broad side of the chisel for wide strokes and the edge for angled lines. Allow layers to dry between applications for uniform opacity, and for non-porous surfaces consider sealing if the item will be exposed to abrasion or washing.

What to consider before purchase

• Intended use: suited for broad strokes and fills rather than fine detail
• Surface type and any required preparation for adhesion
• Durability needs if the decorated object will be washed or handled frequently

Usage recommendations

Store horizontally and recap after use. Test on a small area before applying to final projects, and allow sufficient drying time between coats for the best opaque coverage.
