A treasure box is an instance reward sent to you in the mail after completing a Normal Instance . It is given to you in a message in your mailbox, clicking on the icon on the bottom left of the message makes it appear in your bag (inventory) where you can open it to reveal a random reward. This can consist of one random resource or a blueprint. The blueprint seems to be rare, about a 1/10 drop rate although much debate is if this percentage is accurate. Some players claim that blueprint drop rates temporarily decrease if an instance is heavily farmed, but this is unconfirmed.
