Maybe u should ask around to see if its a reputable brand before placing an order? but if u r like me(not really brand concious) u could give it a try if u really like the colours...
Btw, I think there are other brands that do offer such palattes. I think I saw on ebay the other day this 48 colour MAC lip palatte on sale. The palatte looked huge. In fact, it was the biggest lip palatte I've seen so far...
