Chartpak: I initially sent an inquiry for Grumbacher products, and Chartpak mailed me a list of products of several of their brands, suitable for vegans. On the list were Koh-I-Noor USA, Grumbacher, Chartpak Inc., Clearprint, Maco and Higgins. You will find other brands belonging and or being distributed by Chartpak on their website. Unfortunately, after inquiring again about animal testing and animal testing through third parties, there are bad news . Chartpak let me know, that they are recquired to commission testing for the Northern American market. The conclusion is, Chartpak, Grumbacher, Chartpak inc. and their other brands are not cruelty free.
