This is just one of the many boss keys from the Legend of Zelda game series. This one in particular is nice just because of the detail on the key compared to the older games it is hard to get much detail on something as small as a key.as well as this one does come with jewels to put in the eyes but it looks good without them as well. i would love to see a new jewel for the eye seeing as mine does not look good at all.
