WoW! This eco-friendly, A5-sized notebook is made from tree-free paper with approximately 64 sheets/128 pages of (170 gsm) cream-coloured lined paper. The paper is made from natural stone: 80% calcium carbonate and 20% resin (HDPE) to bind the stone. The cover is also made from 950 grams of stone paper with a Thermo PU finish. This booklet features a handy pen loop, elastic closure and reading ribbon. Stone paper is a sustainable alternative to ordinary paper because far fewer resources are used in production: no trees, no water, no bleach and no chemicals. What makes this product special: in addition to the beautiful smooth paper, it can also be infinitely recycled, providing extra sustainable writing pleasure! The paper is anti-bacterial, waterproof, and tear and stain-resistant.
