Why is で used in this sentence 両方セットで差し上げます?


So I'm reading a manga and this girl is giving a guy two pieces of paper. She
says "正直者ですね。両方セットで差し上げます。” I would think that a を particle would be used here
since the set of papers is an object. "I give the set of papers (to you)."
What do I give? The set of papers. I'm looking here,
<https://core6000.neocities.org/dojg/> , at the 4 main uses of で and none of
them seem to explain the particle's usage here. Can anyone explain what で is
doing here.




Because she omitted the part of the sentence. For example if she was giving
apple(りんご)...

  * りんご **を** セット **で** 差し上げます

... is the correct way. "りんご **を** セット **を** " sounds weird. The example you
have shown omitted the part "りんごを". That's the reason she says "セットで". In the
web site you have shown, I believe で(2) is the closest usage.

By the way, you can also say ...

  * りんご **の** セット **を** 差し上げます

So just saying "セットを差し上げます" is correct too.
