A Badge case is what all Pokémon Trainers use to keep their badges that they have earned. There are 8 slots for eight badges. They make each one different for each region. For Ash, as the years go by, his gym case has gotten more ellaborate. When he was in Kanto and Orange Islands, his badges were kept on a sheet on cloth (see gallery), but in Unova the Badge case was cushoned and fitted for each badge.
