Permanent Black Marker featuring two tips; fine and broad. Two tips are great for drawing, lettering and getting a variety of line widths. Long lasting marker gives a very black, solid line. The oil-based ink is smear proof and can be colored overtop with Dual Brush Pens instantly even on very absorbent paper. Tips stay fresh and firm – no ‘mushing down’ of tips. Ideal for professional fine art & craft.
