Felt tip pens magic marker
Pens also known as fountain brushes, the most common name is Magic Marker, the popular commercial Felt-Tip Pen. As a drawing and coloring device, these pens are easily controlled and have colored ink reservoirs of soluble dies that make them handy for sketching. However, they are not permanent enough for lasting fine art. The tips are available in a number of shapes from blunt to fine point. They are considered non-toxic. American artists who have used these markers on 'finished' artwork include Jackson Pollock, Andy Warhol, Tom Wesselmann, and Jean-Michel Basquiat.
