Spectra AD 24-Piece Basic Marker Set

The Chartpak Spectra AD Markers are the latest edition the 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 have two nibs that can create four types of lines.
• Our mini tri-nib creates thin, medium, and thick widths on one end, while our flexible brush nib creates a smooth line that changes with pressure.
• Alchohol base with a mild odor
• Roll proof barrel and caps
