Oil-based paint markers are ideal for use on porous and nonporous surfaces, including stone, wood, glass, plastic, metal, leather, ceramic, marble, granite, glossy surfaces, paper and more. Ideal for heavy-duty industrial and professional applications as well as decorative purposes. Quick-drying paint resists water, sunlight, rough handling and various chemicals. Paint is also weatherproof, fade-proof and acid-free making it archival-safe. The pump-action paint marker features a fine bullet-shaped, fiber tip and slender pen-type barrel without a rubber grip or clip on the cap. Vibrant, highly visible opaque colors make bold, long-lasting, crisp lines.
