This item works similarly to a book but has a unique texture. The letter has a limited number of pages (fewer than a book).

When a player “signs” the letter, it becomes sealed and is stamped with the sender’s nickname (just like books record their author).

If the letter is given to another player, it remains sealed, ensuring it hasn’t been opened or read. The recipient can break the seal to read its contents, after which the sealed status is removed. Once unsealed, the letter can be edited freely, and the player can reseal it with their own stamp, creating a new verified sender mark.

This item provides a reliable way to verify the sender’s identity while allowing letters to be rewritten and passed along securely.

I know, a bit of a crazy idea for a mod about books, but I think it's very vanilla and would fit in perfectly
