NotePro notebook offers the durability of a hard cover and flexibility of a wirebound book. Unique patented design allows the notebook to lie flat or fold completely under for increased writing stability. Unique labelling system includes self-adhesive coloured tabs and labels for index, cover and spine. Each sheet is microperforated and college-ruled with space for the date. Sheets are made of acid-free, recycled paper and printed with vegetable oil-based inks.
