Rhodia Orange Notepads have fun, tangerine-colored covers, are available in many interesting sizes, and offer superb writing convenience. They're a favorite of artists, designers, architects and people who need quality paper for graphs, notes, sketching, and hand drafting. The covers are scored, so they fold back conveniently out of the way when the pads are in use. The rigid chipboard back provides the feel and support of a drawing board. Rhodia Notebooks are PEFC-certified , manufactured with materials from sustainably harvested forests. (The Programme for the Endorsement of Forest Certification is an international, non-profit, non-governmental organization which promotes sustainable forest management through independent third party certification of forestry practices.)
