... for which we have not yet received.

[MAJSH]

1. We have received the items you sent except for the perfume atomizer, for which we have not yet received.
2. We have received the items you sent except for the perfume atomizer, which we have not yet received.

Would you please tell me which one is grammatically correct? Is it "for which" or " which" in the sentence above?

1. We have received the items you sent except for the perfume atomizer, for which we have not yet received.

The 'for' is incorrect.?

2. We have received the items you sent except for the perfume atomizer, which we have not yet received.

That is grammatically correct, though the second clause is unnecessary. You said in the first clause that you have not received the atomizer.
