Dixon Paint Markers produce permanent, opaque colors on most surfaces including metal, wood, glass, stone, plastic, leather, vinyl, textiles, ceramics, cement, paper and rubber. These oil-based markers maintain color intensity regardless of the surface to which they are applied. The durable color is lightfast, waterproof and weatherproof. The special valve-action tip prevents dry-out. Dixon Paint Markers feature a sturdy metal barrel and are made in U.S.A.
