Sain's Blackbook

This slightly worn blackbook has a cover that has been personalized with the namesake of the owner. Sain originally used this blackbook to practice various forms of graffiti back home, get signatures from other people who did the same, or otherwise just idly doodle in. He generally keeps it on hand since he didn't always have somewhere to store it otherwise.
He still only really has it now as it remains one of his few personal items left, and now he plans to use it to keep track of his travels.
