Wishing I had a picture of these to show... when I worked in Law Enforcement I met a group of guys who played Dangerous Journys in prison. They were not allowed to have real dice per the prison rules so they made a full set of dice out wet paper. They took layers of paper and wet them and then molded them into dice and when they dried they were functioning dice. They were not perfect but you could tell the difference in all of the dice and they did roll fairly well.
