This is a commemorative keychain from the Metropolitan Police Department for the various security measures taken from the passing of Emperor Showa to the enthronement of Emperor Heisei! This also includes the Tokyo Summit held during this period! It was distributed to those who were involved in the security duties at the time! I believe items with the Superintendent-General's name are quite rare! The outer white box shows signs of age-related stains, but the main body inside does not show much age-related deterioration! However, as it is an old item, there may be some unnoticeable age-related deterioration, so please refrain from purchasing if you are sensitive to such things! The way you display it is up to you, so please feel free to decorate it as you wish!
