posca PC-5M Paint Markers, Red 3-Pack — Reversible Medium Tip 1.8–2.5mm, Opaque Quick-Dry Coverage

posca PC-5M is a set of three water-based, reversible medium-tip paint markers in red designed for precise, opaque colour across more than 50 surfaces.

These PC-5M markers from posca combine a controllable medium nib with vivid, quick-drying water-based pigment, made to tackle everything from sketchbook accents to outdoor craft applications. The reversible tip gives you two consistent line widths in one tool while the formula stays permanent on porous materials and can be removed from many non-porous surfaces. They’re commonly used by illustrators, crafters, hobbyists and makers who need dependable coverage and fine control.

How will the reversible medium tip change my workflow?

The PC-5M features a reversible nib that provides two useful stroke widths without swapping tools. Turn the tip for a slightly thicker or thinner line depending on the pressure and angle, which speeds up switching between outlining, filling, and detail work.

• Reversible 1.8–2.5mm range for varied stroke widths
• Stable bullet shape for predictable lines and fills
• Single marker replaces two tools for faster transitions

What surfaces can posca PC-5M write on effectively?

These markers work on a broad range of materials—over 50 types—including porous and many non-porous substrates. The ink lays down opaque, solid colour on wood, paper, and fabric while also adhering well to glass, metal, and plastics for craft and signage use.

• Permanent on porous surfaces like paper, wood, and fabric
• Removable or erasable on many non-porous surfaces such as glass and glazed ceramics
• Suitable for indoor and outdoor applications after drying

How fast do they dry and how durable is the colour?

The water-based pigment dries quickly to reduce smudging and allows layering. On porous supports the colour becomes permanent and resists wear; on non-porous surfaces it often stays vibrant but can be wiped off if needed with solvents or scraping.

• Quick-drying formula minimizes smears
• Opaque, saturated red for strong coverage
• Good adhesion on rough or smooth surfaces with proper curing

How should I use and maintain these markers for best results?

Shake and press the tip to prime the ink before first use, then store horizontally to keep the reversible nib fed. Cap tightly after use to prevent tip drying and bleed-through when working on thin papers.

• Shake marker and depress tip until ink flows
• Store horizontally to maintain consistent ink flow
• Recap after use and avoid prolonged exposure to direct sunlight

Who is this for: posca PC-5M markers suit artists, designers, educators and DIYers who want a reliable medium-sized paint marker with strong opacity and the flexibility to work across many surfaces. Choose this 3-count red set if you need consistent colour intensity for illustrations, signage, mixed-media pieces, model detailing, or craft projects where control and coverage matter.
