Marker POSCA Uni-Ball PCR-3 White — replacement nibs compatibility PC3 M

POSCA Uni-Ball PCR-3 White is a replacement nib solution designed for use with PC-3M-compatible tips. Supplied in a white colour specification, it is intended for precise line work, detailing and quick touch-ups on paper, wood, metal and a range of craft surfaces. The product is compatible with PC3 M nibs and supports consistent application where a thin to medium line is required.

Advantages

This replacement nib option maintains the original PC-3M writing profile for fine and controlled strokes, ensuring uniform ink flow and predictable line width. Being white, it provides high-contrast correction and detailing on darker backgrounds and can be deployed for highlights, borders and small corrections. The design supports straightforward installation into POSCA PC-3M-compatible marker bodies, keeping the marker usable without replacing the entire unit.

Suitable for

• Precise line drawing and outlining on paper and card
• Detailing and highlights on painted wood and craft projects
• Fine touch-ups on metal, plastic and other non-porous surfaces
• Replacing worn or damaged PC-3M nibs to restore marker performance

When it may not be suitable

This product is a replacement nib intended specifically for PC-3M-compatible marker bodies and will not function as a standalone marker. It may not be suitable for creating very broad strokes or filling large areas because it preserves the thin-to-medium line width associated with PC-3M tips. For heavy coverage, broader nib sizes or full-size markers are more appropriate.

Key specifications

• Colour: White
• Compatibility: PC-3M (PC3 M) nibs
• Line width: thin to medium (PC-3M profile)
• Suitable surfaces: paper, card, wood, metal, plastic and typical craft materials

How to use

Remove the worn or damaged nib from the compatible marker barrel according to the marker manufacturer's instructions and insert the POSCA Uni-Ball PCR-3 White replacement nib firmly into place. Ensure the nib is seated correctly before applying ink to the surface. Test the marker on scrap material to confirm flow and line width; perform gentle priming strokes if needed to establish consistent ink delivery. After use, store the marker horizontally with the cap securely closed to maintain nib condition.

What to consider before purchase

• Confirm your marker uses PC-3M compatible nibs before buying
• Intended line width: suitable for fine to medium detail work, not large-area filling
• Colour requirement: white is designed for high-contrast highlights and corrections
• Replacement nibs do not include marker bodies or ink cartridges separately

Usage recommendations

For best results, use the replacement nib with a POSCA PC-3M-compatible marker body filled with POSCA white ink or an equivalent formulation. Work in short, controlled strokes for consistent lines and allow surfaces to dry between layers when applying multiple highlights or corrections. Replace nibs when tips show fraying or uneven lines to maintain precision.
