How is this legal? I see shit like this on Facebook all the time. Also saw a bunch of people selling Attack on Titan merchandise
It would be way too much time, money, and bad publicity for Toei/Fuji TV to go after every single knock off internet company in China selling shit with their branding.
Same for every other business
You have to realize that they probably don't care about the small volume of sales that this company gets and litigation against them would greatly surpass stopping them from selling a product that the company itself doesn't even sell.
