The listing, Mini Notebook with all weather paper has ended.
I really didn't know what category to put this in. I got this sample from the SHOT Show a few years back. The paper will let you write in ink or pencil in all sorts of weather, including downpour. I saw them demo it by putting the paper in a fishtank for a couple of minutes, then pull it out and write on it. Definitely good for someone who needs to take notes outside. Measures about 3"x4". Thanks for looking.
