keep it to yourself

[Nathan Mckane]

Imagine you have lent sth to someone. After he returned it to you, you would tell him that you dont need that thing any more. What would you say :

keep it to yourself
keep it for yourself
Take it for yourself
Take it for you

Thanks in advance.

You could simply say "keep it".

"keep it to yourself" is normally idiomatic meaning "don't tell anybody".
