Ah, Japan, the place that wraps individual carrots and other food items in plastic.
In defense of this, the nature of American cheese would cause all the slices to combine into a single mass.
When I was a kid my mom used to get American cheese sliced behind the deli counter all the time and they always gave us the slices in a stack and it never combined.
I can’t stand American cheese, nasty fake stuff, but I got cheddar cheese slices behind the deli the other week for the first time in awhile. Instead of just slicing it and giving it to me in a bag like every other time in my life, they individually wrapped every slice in a thin plastic. I got home and was like what in the plastic hell is this? So wasteful and it was a real PITA unwrapping it all.
