How legit is the merchandise site?

it would not let me post the link so youll need to look up the the site yourself but it is evangelion merch . com, I was just casually looking it was the top result when searching and it has some shirts that are pretty cool and it ofc says fan site at the top I dont need it to be official but what i was wondering if any of its stolen. like the artwork or designs on the merch or the shirts themself. I have no idea if you just look at the top stuff on google you can see shirts being sold in other places like shein and stuff but i just wanted to know if this site is the origin point or if I should be looking somewhere else
