You don't really have a 'use' for this sealed letter in the traditional sense. It's more of a collectible item. Just keep it in a dry and cool place away from direct sunlight to prevent any damage. When handling it, make sure your hands are clean to avoid getting dirt or fingerprints on it. If you want to store it for a long time, you can put it in a protective sleeve. And don't try to open it as its value lies in its sealed and unplayed state.
