Silver Gauntlets

The Silver Gauntlets originate from Ocarina of Time, and are used to lift heavy objects. They can only be used by Adult Link, and are one of the treasures inside of the Spirit Temple. Nabooru once wished to obtain the Silver Gauntlets from Young Link, but never recieved them due to being captured before Young Link could deliver them.

Finding the Silver Gauntlets
The Silver Gauntlets are found in the Spirit Temple as Young Link in The Legend of Zelda: Ocarina of Time. When Link finishes a series of paths and traps, he arrives outside. There he found a chest which containing the Silver Gauntlets.

Possible Reappearances
There is no reason to believe that the Silver Gauntlets will make a reappearance anytime soon, making it higly unlikely for them to be seen again (though they may be obtained in Phantom Hourglass.)
