The large Decomposition Book features college-ruled paper - 7mm ruled lines printed (using soy ink) in blue, with an adjacent margin in red. The hardcover notebooks have 160 ruled pages (80 sheets) of unbleached white paper made from 100% post-consumer waste. The paper is stitched and the notebook is tape bound, so it opens completely flat and is really tough. The covers are heavy card and, inside, feature all kinds of witty, useful information and sketches. Decomposition BookÂ notebooksÂ are Made in the USA using 100% recycled paper, soy ink and bio-gas.
