Create high impact marks and track, schedule and present clearly. High-quality ink-delivery system ensures consistent, skip-free results, while bold, vivid colors make it easy to see what's written from a distance. EXPO Low-Odor Dry-Erase Markers always erase cleanly and easily from whiteboards and other non-porous surfaces such as porcelain, melamine and glass, simply with a dry cloth or a standard whiteboard eraser; but for optimal results, EXPO whiteboard erasers are recommended. As their ink is specially designed to be low-odor and quick drying, they're the perfect dry erase marker for use just about everywhere: classrooms, offices, homes, boardrooms and more.
