The Japanese thrift stores are much more thorough in checking things, so I imagine they'd catch anything like that and call the person to give it back. Still—I do always look around for hidden treasures when I visit them.

LEGO is really interesting. I'm amazed at how they've been able to pivot the company and change to all these sets, half of which are for adults and super expensive. These days it seems like these lego sets have replaced modeling kits for almost everyone.
