Moricoro Keychain Expo 2005 Aichi, Japan Made of wood The environment hasn't improved at all since the Aichi Expo. Was the Expo pointless? Where did the 30 billion yen profit from the Myakumyaku Expo go? No return. Who and what was the Expo for? Vintage Moricoro, a must-see for enthusiasts! No longer sold, so it's expensive and rare.
