The first impression a Wish fan has when looking for merchandise of this series is: There is *none*! However, if one looks around enough, one does stumble upon quite a few things. (At least far more than one had expected at first).
Below you will find a listing of some products I have come across, especially at places such as Yahoo Auctions and Ebay.

There are quite a number of Wish Phone Cards available,and they all make me wish I had the possibility to bid at the japanese Ebay auctions... *whimper*
Special thanks to Val (not the SnY Val) for saving these images for me during my vacation! *niko-niko*
