We sincerely apologize, but once your shipping invoice has been issued, it means your items have already been packed, sealed, and are ready for shipment. At this stage, we are unfortunately unable to add or remove items, combine with other orders, or split the shipment.
If you have any specific requests, please make sure to contact our Customer Service before the shipping invoice is issued. While we can't guarantee all changes, we will do our best to accommodate your request.
We appreciate your understanding and cooperation, and we are always here to assist with your orders!
