4 inch x 6 inch. 130 pages. 65 sheets. Ruled. Sheets made with bamboo pulp. Bamboo. www.onyxandgreen.com. Bamboo Paper by Onyx & Green is a unique new product that is made primarily with pulp from the Bamboo plant. Bamboo is one of the fastest growing plants on the planet, and bamboo forests create 30% more oxygen than hardwood. Regular paper is made mostly of wood pulp from trees that have been cut down, while the bamboo pulp we use is from bamboo plants that have been cut near the base of the plant that remains alive and will quickly grow back. We hope you will enjoy your new bamboo paper notebook while continuing to protect our planet's trees. Designed in Canada. Made in China.
