The Impact collection stone paper notebook is made of tree-free paper! Stone paper consists mainly of mineral powder (80%) bonded with (20%) of non-toxic HDPE (a clean plastic). Zero water or bleach is used during production, which is the case during the production of traditional wood pulp paper. A tonne of traditional wood pulp paper uses 2770 litres of water and 18 trees. Stone paper is soft to the touch and velvety for ultra smooth writing. 60 sheets/120 pages of 58 gm/m2 white coloured lined. The covers are also fully made of stone paper. Save water and use genuine sustainable materials. With the focus on water, 2% of proceeds of each sold Impact product will be donated to Water.org. Each stone paper notebook has saved 1 litre of water.
