From the anime series One Piece, this is one Die featuring the character Chopper.
Originally from a set of 10 dice produced in 2003, these are the last ones frm the series we have left.
1"x1". Each side is numered and local kids in our area were tossing them when ever they passed in the hallway at school and the highest number won.
Use to replace dice in your exisiting games or make up your own.
