It's like those sliced cheese-looking objects that are a staple of lunchtime sandwiches. But better! Rocket News 24 informs us that the Japanese company Bourbon sells slices of chocolate which, like slices of cheese, can and should be added to sandwiches. You can also use them to fill crêpes, make s'mores, or slip onto pancakes. They come in packages of 60 with thin plastic dividers between the slices.
But I won't lie to you: I'm just going to eat the entire package in one sitting, slice by slice.
