Comment deleted because I don’t want to defend it

This happened to me in 2017 in Mario Odyssey purchased from Walmart, just a single piece of plastic inside of a properly shrink-wrapped case. The return counter said he had seen it many times before already. How has Nintendo not cracked down on their manufacturers allowing this for almost 8 years?

Edit: It would take nothing more than a window in the front case paper to show the game chip inside, not exactly rocket surgery.
