posca PC-1M Extra-Fine Paint Markers — Blue 3-Pack, 0.7mm Tip, Opaque Water-Based Ink

posca PC-1M markers are extra-fine 0.7mm water-based paint pens that deliver opaque, quick-drying colour on 50+ surfaces for detailed drawing and writing.

These PC-1M blue markers from posca come in a three-count set designed for artists, crafters, and makers who need a reliable extra-fine line. The water-based formula lays down vivid, opaque pigment that becomes permanent on porous materials yet wipes clean from many non-porous surfaces. Each marker features a washable, removable nib and a compact bullet tip ideal for precise strokes, lettering, and intricate work.

How precise are the PC-1M markers for fine detail work?

The 0.7mm extra-fine bullet tip gives controlled, consistent lines suitable for outlines, hand lettering, and technical details. The tip holds its shape through regular use and can be replaced or rinsed if paint builds up.

• 0.7mm tip for fine lines and tight areas
• Consistent ink flow for uninterrupted strokes
• Washable and removable nib for maintenance

On which surfaces will the blue ink perform best?

posca PC-1M markers work across a wide range of materials. The pigment is opaque enough to show on dark or coloured backgrounds and sets to a permanent finish on porous surfaces like paper and wood, while staying removable on many non-porous items.

• Permanent on porous surfaces: paper, wood, cardboard
• Visible and opaque on painted or dark backgrounds
• Removable on many glass, metal, and glazed ceramics for temporary designs

Are these markers suitable for indoor and outdoor projects?

Yes—the quick-drying, water-based ink is formulated for versatile use indoors and outdoors. While the pigment resists fading on many surfaces, finishing with a clear sealer is recommended for outdoor longevity or heavy-wear items.

• Quick-drying to minimize smudging during use
• Use a clear varnish or spray sealer for outdoor durability
• Ideal for signs, decorations, and small outdoor crafts when sealed

How do I maintain and store the markers to extend lifespan?

Store posca PC-1M markers horizontally to keep ink distribution even and recap them after use to prevent drying. If the nib clogs, remove and rinse it under water; the washable nibs make cleaning straightforward.

• Store horizontally for balanced ink flow
• Recap tightly after each use to avoid drying out
• Rinse removable nibs under water to clear buildup
