If I did a trade with a player
And gave him a Item of Almost (I gave him a more expensive Item) Equal Shop Value
And he wants that item back must I return it?
(Note I Gave said player a Arcane Dagger of Haste [375k From Luxury Shop]
In Exchange for Fiery Axe [350k From Luxury Shop]
NOTE2 HE ASKED FOR THE TRADE AND DID NOT ASK FOR ME TO GIVE BACK
So Said Player wishes for the axe back And I'm wondering Am I breaking any rules if I do not return said item?

EDIT:: He asked for the item The next day if I didn't make it clear
EDIT2:: He did not ask me to make any such promises to give it back if he did not like the Arcane Dagger

You don't need to return anything. All trades are final.

No you are not

Oh, That's a relief Ty for clearing my mind
