Please show me example sentences with those which . Tell me as many daily expressions as possible.

See a translation

I don’t hear “those which” very often.

You could say:

A: what else do you need help with?

B: Would you mind carrying those, which need to go back to the office?

(In this situation, person A and B are cleaning/organizing and “those which” can specify where the item goes)
———-

A: Do you have everything you need for your trip?

B: Yes! Oh, except those, which I’ll need for the plane in case I don’t feel well.

(In this instance, person A and B are talking about a specific item and using “those which” to explain why it is necessary)

Often people will probably just say the item’s name or “those + item” such as “those papers, which”.
