Choose a good courier: SF Express or EMS. I buy a mobile phone and send it by EMS.
You can also inspect the goods before signing for them. If he says no, you can say to him: I refuse to accept them. Anyway, I won't sign for them without inspection. Under normal circumstances, they will compromise.
Another is that you take the label after signing for it and give it to him after inspection. If the goods are not right, you will not give them to him decisively.
