posca PC-1MR Extra Fine Paint Markers — Black 3-Pack, 0.7mm Precision Tip, Opaque Water-Based Ink

posca PC-1MR is a water-based extra-fine paint marker (0.7mm) for precise, opaque lines on more than 50 surfaces.

These pocket-sized paint pens bring the coverage of paint with the control of a pen, making them useful for detailed artwork, labeling, and upcycling. The 0.7mm calibrated bullet tip balances fine handwriting and crisp line work while providing vivid, quick-drying opaque colour. Because the formula is water-based and non-toxic, it’s versatile for indoor and outdoor projects: permanent on porous materials and removable on many smooth surfaces.

How precise are the PC-1MR markers for detailed work?

The 0.7mm extra-fine tip is designed to deliver consistently narrow, controlled strokes for small-scale detail. The calibrated bullet point resists splaying and keeps a steady line width, so lettering, intricate patterns and fine outlines come out cleanly.

• Tip diameter: approx. 0.7mm for hairline and micro details
• Calibrated bullet tip stays resilient during pressure
• Opaque pigment ensures visible, single-pass coverage

What surfaces can I use these markers on?

posca PC-1MR works on more than 50 surface types, from porous woods to slick metals. The water-based paint adheres permanently to porous materials and wipes or peels from many non-porous surfaces, giving creative flexibility for mixed-media and functional marking.

• Porous: paper, wood, fabric—dry-to-permanent finish
• Non-porous: glass, metal, plastic—often removable or wipeable
• Also suitable for ceramics, leather, and painted surfaces

How do I use and maintain these paint markers for best results?

Shake each POSCA marker well before use to blend the pigment, and press the nib gently on scrap until the pigment flows. Replace the cap after use and store horizontally to prolong tip life; the felt tip is washable and replaceable if you need to refresh it.

• Shake and prime on paper until ink appears
• Cap securely and store flat to protect the tip
• Washable tip for easy cleaning; cap fits on pen end during use

Can these markers be blended, layered, or used outdoors?

Yes—because the ink is water-based, you can blend and dilute the pigment with water or layer once dry for richer saturation. Quick-drying properties make them suitable for outdoor applications, though longevity depends on the surface and exposure to elements.

• Dilute and blend wet-on-wet for gradient effects
• Layer dry coats for deeper, opaque coverage
• Outdoor use possible; test on the intended surface for permanence

Who this is for: Artists, crafters and makers who need a compact, precise paint marker will appreciate the posca PC-1MR. It’s ideal for illustrators adding fine highlights, scrapbookers and journalers who want clean lettering, modelers detailing small parts, and DIYers refreshing household items. Because the markers are non-toxic but not intended for children under 12, they suit adult hobbyists and students working on detailed projects.
