"Hello
There's been a lot of talk regarding the North American and Japanese promotional campaigns. We are working to setup campaigns in PAL regions with the new in-game items. They will also be available for purchase on the Mog Station at a later date. We will share more information as soon as it becomes available.
Please note that the North American and Japanese item codes won’t work on EU accounts."
