the inferno/paradiso one is real. It was free with a purchase of tokidoki bags at nordstrom last year when simone came for signing. The one on tokidoki.it is the first version of the uchiwa. And I think there's another hawaiian version uchiwa too.
The uchiwa is paper, though, right? I guess it'd be more of a collector's item than something you really use... Paper uchiwas get dirty and damaged when you use them. The one on the tokidoki website is really cute though!!
