Permanent black marker featuring two tips; fine and broad.  Two tips are great for drawing, lettering, and getting a variety of line widths.  The 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.
