These eco-friendly notebooks use paper created through a unique process that uses by-products (like rinds, skin and pits) from organic fruits that would have otherwise ended up in a landfill. Paper produced from fruit reduces the need to use virgin tree pulp, therefore saving forests. The color of the sheets of paper is determined by the fruit used to produce it. The Paper is FSC (Forest Stewardship Council) certified, confirming the paper is made from responsibly sourced fiber.
