Whiteboard markers are special pens designed for writing on non-porous surfaces, such as whiteboards. They contain a water-based ink that can be easily wiped off with a dry cloth or eraser, making them ideal for classrooms, offices, and presentations. The ink dries quickly, preventing smudging and allowing for clear visibility. These markers come in various colors and tip sizes, catering to different writing styles and preferences. Some whiteboard markers are even designed with low-odor ink, making them suitable for enclosed spaces. Proper storage, such as keeping the caps on when not in use, helps maintain their longevity and performance.
