Rite in the Rain All-Weather Top-Spiral Notebook, 8 1/2" x 11", Black Cover, Universal Pattern (No. 785) WEATHERPROOF PAPER: 100 pages / 50 sheets per large notepad. All-Weather paper wont 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.
