"These are sold only in-store at the Studio Ghibli Museum's gift shop in suburban Tokyo (it's like candyland for Miyazaki stuff, I wish I'd bought more when I went there in '07), but you can also pay a few individuals who will go to the museum, buy the item, and mail it to you for a commission (which is what I did for this guy this year). The base price of these giant things is already high, and shipping for something that huge can also add something fierce. Let me just put it this way: I'm not going to let him barf on it anytime soon
If people want more details I'm happy to help."
