WEATHERPROOF PAPER: 64 pages / 32 sheets per side spiral notepad. All-Weather paper won&';t turn to mush when wet and will repel water, sweat, grease, mud, and even survive the accidental laundry mishap. Make sure your pocket notebook stays RIGHT in the Rain. WIRE-O BINDING: Tough impact-resistant Wire-O binding won&';t lose its shape in your backpack or book bag. Unlike a standard spiral notebook, Wire-O keeps your open pages aligned and intact. WRITE IN THE RAIN: Use a standard pencil like a #2 Ticonderoga or an All-Weather Pen like a Fisher Space Pen and your notes will stay intact. Standard Ballpoint pens will work when paper is dry. Water-based inks will bead off Rite in the Rain paper sheets. WATERPROOF NOTEBOOK COVER: Polydura material creates a tough but flexible outer shell. Whether you&';re needing a hiking journal, outfitting your police gear, starting a golf journal, or just keeping a shower notebook, the Polydura Cover material will defend your field notes from scratches and stains. RECYCLABILITY: Unlike synthetic waterproof paper, wood-based Rite in the Rain is completely recyclable. Please recycle Rite in the Rain as you would other white or printed papers.
