Oversized and undersized items

It is a Bethesda tradition to add giant versions of items to their games, and Fallout 3 and Fallout: New Vegas are no exception.

Oversized and undersized items are items which are scaled larger or smaller than normal.

They can be used as unique decorations for your house. Items of unusual size exhibit slightly peculiar behavior compared to "regular" objects, you can pick them up from where you found them and drop them somewhere only once. You can keep them in your inventory or in storage indefinitely (though you won't be able to tell them apart from a regular item of the same type). Drop them on the ground and they will still retain their size, however if you pick the item up and drop it again, it will lose its "special" size and become a normal object.
