The Kit Kat King Size is a delicious combination of smooth milk chocolate and light, crispy wafers, in a size you can share. This super sized Kit Kat chunky bar was a gift from an old friend from Australia. It has been months since I received this guilt-filled confectionery yet I have not gathered enough courage to take a bite of it. Kindly advise me when I should to unseal it and permanently discard it from the refrigerator. Now or never?
