I think you misunderstanding my point. Mrs.Cha will visit HK show and pick up the necklace when she visits the show.
That menas I do not have HK office address to give you.
Also, for the payment, she will make it when she is in HK by cash. I just asked the bank detail just in case, she do not have enought fund to hold in HK.
If you need more information, do not hesitate to contact to me.
Thanks
