SKU: K Chartpak® AD® Marker Art Director Set, 25 Markers The Art Director set is made up of blue, green, brown, and gray color families. Individual accent colors for red, yellow, orange, and pink are included as complimentary to the main color families. This set contains bold colors for a variety of design-oriented projects. Chartpak's original xylene AD® Markers properties are unlike all alcohol-based markers common to the marketplace, and while they are compatible with one another, they perform very differently. They won't smudge alcohol-based pens including fine liners, they also work well over ballpoint pens and technical pens. To mix a custom color, apply the marker colors to a plastic film like acetate, pick up the marker color and mix them with the Colorless Blender (sold separately) as you would a paintbrush. Once mixed, you can use the blender marker to apply your custom color to your surface. AD markers layer, blend, transfer laser images, and are permanent on many porous and non-porous substrates. However, they are not recommended for use on Styrofoam. These markers are juicy, and last an extremely long time when the cap is applied securely. There is no mistaking the scent of a xylene marker, and for this reason, we always suggest using them in a well-ventilated area. All markers come with a tri-nib point allowing for thin, medium, and broad strokes all within one marker. The nibs are removable and replaceable to extend the life of your marker.
