Permanent black ink marker featuring twin tips- a fine tip (.4mm) on one end and a broad bullet tip (.8mm) on the other.
This twin tip selection is great for making a variety of line widths with both drawings and lettering. Tips stay fresh and firm instead of mushing down or fraying like other markers.
Long-lasting marker gives a very black, solid line. Ink is smear-proof and can be colored over with dual brush pens instantly even on very absorbent paper.
