RAW Classic is crafted from vegan, unbleached plant fibers and finished with the purest natural tree sap gum line. Because they contain a hybrid blend of unbleached (not chlorine whitened) fibers, the paper is a translucent natural light brown color. Each paper is watermarked with our patented Crisscross watermark. This special watermark helps prevent runs and maintains the smooth even-burning characteristics that RAW is famous for. Classic Paper Material: Natural, unbleached paper. Vegan and chlorine free.
