- "Inside the envelope is a picture of a beautiful young woman of the Sheikah tribe."
- — In-game description
The Classified Envelope is a key item in The Legend of Zelda: Breath of the Wild. Link can obtain it from Symin at the Hateno Ancient Tech Lab as a reward upon completion of the Hyrule Compendium. Like Hestu's Gift and Kilton's Medals of Honor this item functions as little more than a trophy awarded to Link in recognition for his achievement and obtaining them is entirely optional. Symin reveals he found the envelope hidden inside a book, which apparently contains a picture of a young Sheikah woman, who due to its location in the Hateno Ancient Tech Lab is implied to be the lab's director Purah taken either one hundred years ago or during the time she was working on her reverse aging rune experiment.
