Dear Champ,
19/F to 27/F glass order will have 3 POs each floor for typical, non-typical and special glass, so the supplier will mark of this.
For example : PO : 9100016772/9100016773/9100016774 for 27/F so that supplier marked of packing list, can we mark of that 9100016(772/773/774) for yours?
Thanks
Johnny NG
