Used, Functionality Confirmed Sanrio Greeting Card This card plays music. When you open the card, "We Will Rock You" plays! I've opened it a few times to check the sound. Currently, the music plays without any problems, but I don't know the remaining battery life. (The battery is not replaceable) There are no noticeable scratches or stains, but please purchase only if you understand that this item has been stored at home and has been handled by someone else. Recommended for Queen fans!
