Din's Charm

You can receive Din's Charm after you've found her a house in Hyrule Town. After doing so she will offer you one of her charms, she will give you one if you have an empty Bottle. In addition to this she will always give you her charms for free, but you can only carry one of Din's Charms at a time. Her charms also boost Link's attack for a limited amount of time and her charm will turn Link orange and his eyes red if he uses it in the Hyrule Town Cafe, but normally Link's tunic will just turn red.
