Example Input: These notepads are difficult to write on with a Fisher Space Pen. It does work, but the writing is rather splotchy. Works great with gel ink (but may smear), and is alright with regular ballpoints. It repels water on the surface, but the edges allow water to seep in, so underwater writing may not be a good idea.
Example Output: 3
