Aluminum sanshin case. It's about 20 years old. I don't think this type of aluminum case is sold anymore. There is metal damage due to aging, circular marks on the case surface, and sticker marks from air travel, but since it was only used for storage, there is no damage from use at all. Please refer to the photos. It has excellent protective power and style. It will be shipped wrapped in recycled bubble wrap. Thank you very much. #Sanshin #AluminumCase #Okinawa #OkinawanFolkMusic #SanshinHardCase #SanshinAluminumCase
