Our ‘tree-free’ A5 Stone Paper Notebook is made from high-quality, sustainable stone paper. Stone paper consists of mineral powder bound with non-toxic HDPE (a clean plastic). No water or bleach is used during production, which is the case during the production of traditional wood pulp paper. One tonne of traditional wood pulp paper uses 2,770 liters of water and 18 trees. This beautiful A5 stone paper notebook uses zero! Our unique, eco-friendly notebook is bright white and acid-free.
