Whiteboard markers are special writing tools designed for use 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 meeting rooms. The markers come in various colors and tip sizes, allowing for clear and vibrant writing. These markers typically have a felt tip that can produce fine or broad lines, depending on the user's needs. They are often used for presentations, brainstorming sessions, and teaching, as they allow for quick changes and corrections without leaving permanent marks.
