A dry erase marker is a special pen designed for writing on non-porous surfaces, like whiteboards. These markers contain a unique ink that can be easily wiped off with a cloth or eraser, making them perfect for classrooms, offices, and homes. They come in various colors and tip sizes, allowing for creativity and clear communication. Using a dry erase marker is simple and convenient. Just write your message or draw a picture, and when you're done, you can erase it without leaving any residue. This makes them a popular choice for teachers, students, and professionals who need to share ideas quickly and efficiently.
