You can find it here on Ebay:

Not to be negative, but that many designs at that price? I strongly doubt that they are legal. Of course, everyone can do as they wish, but I would pretty much bet that the "collection" there is pirated.
They aren't "official" Bratz, but there are some designs around that resemble the Bratz dolls. For instance, check out http://www.designsbyms.com/sivigl... I hope you find what you are looking for. =]
