They not adding them to the NA store, the store didn't know what I was talking about and said to contact SE main support and this the response I got.

Thank you for contacting SQUARE ENIX support,

Unfortunately these were brought especially for Fan Festival this year. We can say that we will take your request into consideration regarding selling them on the North American Store, but I cannot guarantee we will be able to do so.

Thank you for contacting the SQUARE ENIX Support Center.
