Stamps are craftable items that are required to ship letters via the Mailbox in SMP. Stamps come in all different types, ranging from 1n (cheapest) to 10n (the most expensive). The higher the value of the stamp, the more items that can be attached to a letter. For example: A single 1n stamp is enough to send just a letter with nothing in it aside from text. If you were to include an item such as a book or a diamond, you would need to add another 1n stamp (two 1n stamps to cover the cost of the letter and the attachment), or a 2n stamp (the equivalent of two 1n stamps), and so on and so forth based on how many attachments your letter contains.
