Chartpak Spectra Markers

Spectra AD™ Markers are an alcohol-based twin tip marker that 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 capacity allows for maximum draw out, and the twin nibs offer the artist a wide range of line options in one marker. Available individually and in sets. Spectra AD™ Markers come in 95 colors and a blender and are refillable.

​The colorless blender lightens other Spectra AD™ Marker colors, can be used to create custom colors by mixing marker inks on acetate, and can create gradients.
