Chartpak SPECTRA AD COOL GRAY 12 SET
Spectra AD Markers are extremely versatile, featuring dual-ended tips with a flexible brush tip on one side and an innovative Tri-nib on the other. These brilliant alcohol-based markers are ideal for both art and design. The AD Marker signature Tri-nib offers three line widths – fine, medium and broad – with a twist of the wrist. Colors dry fast and are permanent and non-toxic. They can be used with the Spectra AD Blender to create gradations, to blend and to lighten color. They can also be used with traditional xylene-based markers.
