The Carhartt Please Notebook Set is made in collaboration with Sydney brand Karst, which specializes in premium notebooks made from stone paper. This is an alternative to traditional paper pulp that does not use trees, water, waste, acids or bleach. The set contains two A6 books, each with 50 waterproof and tear-resistant pages. The notebook's covers are made from flexible vegan leather and are detailed with a gold colored print. They also have expandable back pockets for storage.
