Mail is a special type of held item that can contain messages written by the player. Similar to a book and quill, the contents of mail can initially be freely edited by any player. The name of the player who writes the message will be automatically placed at the bottom-right corner of the message. Once the message is finished, the mail can be sealed in order to prevent it from being edited.
Mail comes in thirty different designs that all derive from various Pokémon games.
