Claim Check

In Ocarina of Time, the Claim Check is used to obtain the Biggoron's Sword. It is the final item in the Trading Sequence, given to Link by Biggoron in exchange for Eye Drops. If Link shows Biggoron the Claim Check after three days, he will give Link the Biggoron's Sword. The Claim Check will remain in Link's inventory for the rest of the game.
