This Tri-Nib Chartpak marker gives you three distinct line weights in one nib! The markers deliver sparkling and brilliant color in fine point, medium weight or broad strokes - with just a twist of the wrist. The unique shape of the Tri-Nib gives you precise control over your stroke, and the wide palette of permanent colors, which includes a complete range of pastels and grays, opens new worlds of creative possibility. These professional, xylene-based markers are a tried and true favorite amongst artists and designers.
