They're fine when sent to the US and most other 
countries but they apparently aren't accepted in 
Japan.
Its the main reason why I've only ever made one 
order from Animetaro. 
I just feel a bit uncomfortable sending cash in 
the mail. And getting US dollars in less than 
US50 dollar denominations here is difficult.
I guess our IPMOs are not quite as International 
as the US ones are.
