Create bold, permanent marks on a wide range of surfaces with Dixon medium tip paint markers. This 12-count pack includes blue oil-based markers that produce opaque color on materials such as metal, wood, glass, plastic, stone, rubber, and cardboard. The durable color is designed to stay vivid and is lightfast, waterproof, and weatherproof for indoor or outdoor marking projects.
