Rothco's All Weather Waterproof Notebook allows you to write anywhere, even in the rain! The spiral notepad features a PVC cover with waterproof bonded paper, making it ideal for taking notes in any kind of weather. Your writing won't wipe off, even through water, sweat, humidity, grease, while the paper won't disintegrate when completely wet. Great for military, survival or camping purposes. Use a Pencil or All-Weather Pen and your notes will stay intact. Standard Ballpoint pens will work when the paper is dry.
