Marking materials are substances used to create visible marks on various surfaces. Common types include markers, highlighters, chalk, and paint. These materials are essential in educational settings, art, and industrial applications for labeling, drawing, or emphasizing important information. Different marking materials serve specific purposes. For instance, permanent markers provide long-lasting marks, while dry-erase markers can be easily wiped off. Chalk is often used on blackboards, and highlighters help emphasize text in books or documents. Choosing the right marking material depends on the intended use and the surface being marked.
