Alright, I collect some opinions and then I decide if and how I'll do it.
As the FP is a poster, shipping will be more expensive for sure. You have to consider that.
Apparently those are the covers for the Music Cards (post card alike this time):
They're called "Summer Greeting Music Cards".
Thanks to her offical site and Koda Kumi Italian Fanclub on fb
And I just took a look on the original message.
FC goodies are:
Koda Gumi: colourful uchiwa (a fan) + HOTEL poster
playroom: limited FC poster + HOTEL poster
The HOTEL poster is also the FP goodie.
And MONEY IN MY BAG will be an upbeat number.
Though I absolutely don't know what gorigori means for a song. Normally it means to scratch. xD
