Exacompta Chartwell Watershed Waterproof Notepad has been designed for use in the most adverse weather or site conditions. Using synthetic paper to ensure water resistance, each page accepts pen and pencil while remaining tear resistant. The durable vinyl cover is hardwearing and impervious to water and many harsh chemicals, making this Pad ideal for use on site or in demanding weather conditions. Wire binding means it can be folded back upon itself while portable or laid flat on a desk.
