The 4" x 6" top spiral notebook is small enough to fit comfortably in your pocket and tough enough to survive any of Mother Nature's onslaughts. This scrappy pocket notepad will survive rain, sweat, mud, snow, oil, and grease. Impact resistant Wire-O binding won't lose its shape when tossed around in packs or put in a back pocket. The Polydura cover defends your field notes from scratches and stains. Each notepad is printed with a standard and metric ruler on the back cover. Rite in the Rain All-Weather Writing Products have been made in Tacoma Washington, USA since 1916. Recycle Rite in the Rain Paper with standard papers. Recycle the entire notebook using most curbside programs (paper, plastic, & metal). Simply separate the Wire-O binding from the cover prior to recycling for easier processing.
