Chartpak Spectra AD Markers

Spectra AD™ Markers are the latest edition to the AD® Marker family. An alcohol-based twin tip marker features brilliant color with less odor than the traditional AD® Marker. Painstakingly developed over several years, Spectra AD™ Markers were designed tip to tip, inside and out, with the artist in mind. Each air-tight cap closely matches the marker's ink, the barrel is ergonomically shaped and prevents rolling, ink capicity allows for maximum draw out, and the twin nibs offer the artist a wide range of line options in one marker. Spectra AD™ Markers come in 95 colors and a blender.

Brilliant alcohol based markers in 95 colors and blender are ideal for art and design.
Extremely versatile, featuring dual ended tips with a flexible brush tip on one side and a unique
tri-nib on the other.
The AD Marker® signature Tri-nib offers three line widths – fine, medium, and broad –
with the twist of the wrist.
Colors dry fast, are permanent, and non-toxic.
They can be used with the Spectra AD™ Blender Marker to create gradations, to blend and to lighten color.
Spectra AD™ Markers can be used with traditional xylene-based AD Markers®. Conforms to ASTM D-4236.
