Hi, Ihave a kind of stupid question. HAC is not exactly birkin. It is Haut a Couirrous (?), right? So, it is not officially birkin. Then, what about JPG? Is it birkin or it is something else like HAC? On a receipt, what is it going to say? Is it going to say JPG birkin or simply JPG? I have not received my JPG shipment yet. So I don't know how the receipt will say. Please anyone teach me about JPG-shoulder birkin(?).
