The CONCORDE OHP M permanent marker is an ideal choice for the office, school, and workshop. Thanks to its alcohol-based ink, it creates an opaque, durable, and fast-drying line that adheres well to both smooth and porous surfaces. The medium M tip, 1–1.5 mm, ensures clear and professional marking.
Use it for overhead projector films, as well as on glass, plastics, wood, and metal. The ink is indelible and water-resistant, making it suitable for permanent marking and archiving.
