The reputation of the Chartpak portfolio for quality and leadership has been a standard within the design, drafting, and engineering industries for over 60 years. While Chartpak products have been used in the fabric of American creativity from the likes of Norman Rockwell to NASA, our brands have humble roots. Nearly all of the brands Chartpak has incorporated into its family have started as passionate ideas of artists and innovators and have grown to become household names, such as Grumbacher®, Higgins® and Koh-I-Noor®. With this common thread, Chartpak continues to expand its family of legacy brands.
