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. Use 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. Each pump-action, paint marker features a medium-sized, bullet fiber tip and wide-style barrel. Markers include an ergonomic rubber grip for added comfort and a durable pocket clip on the cap. Vibrant, highly visible opaque colors make bold, long-lasting, crisp lines.
