The Coloring Markers are drawing and coloring tools consisting of a cylindrical container filled with colored ink, equipped with a porous tip, typically made of fiber or plastic, that releases the ink onto the surface it is applied to. They come in a variety of colors and line thicknesses and are primarily used for coloring, highlighting, sketching, and marking text. Markers are popular in schools, offices, for art, and drawing, valued for their ease of use and color durability.
