I dunno if they are or not. Most likely not. Just companies just want to make their own merchandise.
I just bought an Ayumi Towel Box from this Singapore seller on Yahoo Singapore. I lost the picture of what it looks like though. Very cute and would flaunt my Ayu fan craze off to everyone and want them to listen to her.
The question is guys, if you saw Ayu on an unmerchandised product, would you still buy it?
