This is a collaboration item between Hong Kong MTR and SONY. Distribution ended many years ago, making it a rare item that is not available in the used market. I obtained it when I lived in Hong Kong and have kept it in a dark place until now. Please confirm the condition in the photos and purchase only if you are satisfied. The train says: "Fun, unstoppable! Unblockable! With Sony by your side, you're always happy! like.no.other" Hong Kong advertising train subway
