What if an incredible life changing idea suddenly comes into mind but your are 130 feet below the pacific ocean? How are you ever gonna write that detailed diagram and draw those lovely stick man figures before you forget it!? Lucky for you there is the Waterproof Notebook. The pages on this notebook are made of durable water resistant stone paper that have perforated lines on the inner edge for an easy quick tear. It also comes with a 100% graphite pencil which is also waterproof. Sure the closest thing you’ll be to that scenario is your bathroom shower but hey it’s always better to play it safe.
