Pantone Tria markers

Pantone Tria markers are a line of alcohol-based art markers marketed by Letraset. They are notable for having a total of 300 colors that correspond to the Pantone color matching system, as well as for having three separate polyester nibs (two, on one end, are fine and medium fine, and the other end is broad). Markers are commonly sold individually in art speciality stores, and can be purchased online in packs of 12. Letraset also produces bottles of refill ink for the markers.
