The Avery Pen-Style Dry Erase Markers (AVE 24459) are designed for use on whiteboards, glass, and other nonporous surfaces in business and educational environments. This 4-pack includes markers with black, red, blue, and green ink, each featuring a medium bullet tip for clear line creation. The low-odor, nontoxic ink is formulated for high visibility and easy dry-cloth or eraser removal. A key feature is the cap-off ink, which prevents drying for up to 24 hours if the cap is accidentally left off. These markers are suitable for office presentations, meeting room whiteboards, or classroom instruction, providing a reliable tool for temporary written communication without smudging or ghosting. They offer a practical solution for organizations requiring consistent, erasable marking capabilities.
