When opened, the bookrests, page holders and back stand automatically fold out, providing solid, angled support for most sizes of book or even an electronic tablet device. A non-slip foot at the base of the spine keeps the unit in place on the work surface during use. When closed, CookBook™ folds flat, becoming no thicker than an average-sized book (approx. 20mm). Made from high-quality ABS plastic, CookBook™ is also tough, stylish and easy to clean. Wipe clean with a damp cloth.
