Dry-erase markers are special pens designed for writing on non-porous surfaces, like whiteboards. They contain a unique ink that can be easily wiped off with a cloth or eraser, making them perfect for classrooms, offices, and homes. These markers come in various colors and tip sizes, allowing for creativity and clear communication. Using dry-erase markers is simple and fun. You can jot down notes, draw diagrams, or brainstorm ideas without the mess of traditional ink. When you're done, just wipe the board clean and start fresh. They are often used alongside whiteboards and flip charts for presentations and group activities.
