posca white paint marker set — Ultra-Fine to Fine (PC-1MR, PC-1M, PC-3M) | opaque matte coverage, multi-surface

Posca's three-pen white set delivers crisp, opaque paint lines from 0.7mm to 1.8mm for precise detail work on almost any surface.

This compact kit combines three of Posca's smallest white paint markers—PC-1MR, PC-1M and PC-3M—so you have ultra-fine to fine tips ready for illustration, labeling, crafts and repairs. Each pen contains water-based, pigment-rich white ink that lays down bright, opaque coverage that dries to a matte finish. The pack is geared to artists, hobbyists and makers who need reliable white on dark or textured backgrounds without bleeding or translucent streaks.

How do these Posca pens differ and when should I use each tip?

Each nib size gives a distinct line width and control for different tasks: the PC-1MR micro-roller is for the finest accents, the PC-1M supplies a steady ultra-fine line, and the PC-3M covers slightly broader fine details. Choose the nib that matches your stroke needs—tiny highlights, crisp outlines, or thin fills.

• PC-1MR: approx. 0.7mm micro tip for hairline details and precise dot work.
• PC-1M: approx. 0.9–1.0mm for fine lines, lettering and tight contours.
• PC-3M: approx. 1.3–1.8mm for thin fills, borders and visible highlights.

Will the white paint work on different materials like glass, fabric and metal?

Yes — the water-based pigment formula adheres well to many nonporous and porous surfaces, providing opaque white coverage. While the paint bonds to glass, metal, plastic, stone, terracotta, porcelain and fabric, adhesion and durability vary with surface preparation and use conditions.

• Use on prepared, cleaned metal and glass for crisp marks and minimal smudging.
• Apply to fabric and porous surfaces; test first for washfastness or seal if needed.
• Porcelain and terracotta accept bright, opaque strokes—seal for durability if required.

How do I get the best performance and longer life from these Posca markers?

Prime and store the pens correctly to maintain ink flow and tip shape. Shake and press the tip as instructed before first use to activate the paint chamber, recap after use to prevent drying, and keep them stored horizontally for balanced ink distribution.

• Shake each pen with the cap on to mix pigment before priming.
• Press the tip gently on scrap paper until paint flows smoothly for the first time.
• Recap after use and store horizontally away from extreme temperatures.

Are these Posca markers easy to use for lettering and small repairs?

The ultra-fine to fine tips make this trio especially suited for precise lettering, highlights and cosmetic fixes where a discreet white mark is needed. Their opaque white ink hides dark backgrounds well and dries to a matte finish, so lines remain visible without glare.

• Excellent for crisp lettering and tiny signatures on dark paper or coated surfaces.
• Useful for touch-ups on small chips in ceramics, painted objects, or craft projects.
• Layerable for increased opacity or subtle texture without bleeding.

Who is this for: This Posca white set is aimed at illustrators, mixed-media artists, crafters, model makers and anyone who needs reliable, opaque white detailing in ultra-fine to fine widths. If you work on dark papers, ceramics, glass, plastics or small-scale projects that demand clean, controlled white lines, this three-pen pack gives you the most commonly used small nib sizes in one compact kit.
