Hi All, I'm new to the fallout series but not to Role playing games, I am confused as to what I do with bobbleheads, I know what they do, but does the perk get automatically rewarded or do I have to hand it in anywhere? many thanks in advance.

It's automatic and persistent. They don't weigh anything, IIRC, so you can lug them around or put them on display in your home.

They are pretty.

There's a stand.

My collection of bobbleheads must be broken. None of them seem to actually bobble.
