I might be reading this wrong, but it seems that there's an import ban on these magnets? From the first item in the FAQ in the article: "Even though Zen Magnets and the included warnings have been found to be without flaw, there is still a nationwide import ban."

Edit: This [0] is linked to elsewhere in the discussion. It seems to support the assertion that there's an import ban.
