It looks edible, but it's actually 16 magnets.
I have not figured out why you might want this, but it is available in case you do want it. From the description:
"A magnet that looks and feels like real chocolate, but tastes like wax. The novelty of these clever magnets is that they are packaged as a complete chocolate bar in which you can break off squares to use each magnet on a piece by piece basis. 15 piece chocolate bar."You can buy them at Up to You Toronto>>
