She comes in a GSC box. This is the first time I bought a figurine that is not ordered from the internet. I have a suspicion that the one I got is an imitation, since it's a little cheaper than the one sold in the net. Also asked the dealer how he pays customs taxes, all he said is that his "suppliers" have a way of getting around customs.
Well, even as an imitation. Madoka-san is cute enough, so I bought the figurine.
