Cuz Japan does it, and that makes it okay? I've bought a lot of Japanese blind box figures when they were Japan exclusive. Kinnikuman Statuettes, One Piece figures with candy...
As I said, I'm not one of those guys who goes out and collects the trendy Kidrobot "Obscure artist PVC bears puking" figures, but I'll definately pick up these Fraggles.
And as I recall, they wanted a set they could sell to comic book stores that come with letters (for no reason) that are blind box, and a smaller run of letterless window boxed figures. I hope they just give up the former, and give us the latter.
