Hermes birkin 25 in croc

I just saw this bag from http://ebbaaggs.com/. It is not made of true croc leather. It is made of calf leather. But I think they looks amazing! Unit price is 458 usd. If you want birkin 25 bags in croc leather,unit price is 18000 usd. And it is just a replica birkin 25 bag.Too expensive!!!
