They recently opened and carry licensed?/collaboration? Aoki Misako ribbons and totes: http://store.kawaii-girl.jp/kawaii_en/products/list.php?category_id=491
They also have stuff from a brand called Baby Ribbon.
I'm fairly certain they are legit. They run a website (http://www.kawaii-girl.jp/) and youtube channel where they post videos of figures from the Japanese entertainment industry as well as interviews/photoshoots, etc featuring Aoki Misako. They will be releasing Aoki's first "essay book" too!
Here's their channel: http://www.youtube.com/user/kawaiigirljapan
I like their channel because they put subtitles on all of their videos.
Anyway, just wanted to point this out :)
