Scaled items (Fallout 3)

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

Characteristics
They can be used as unique decorations for houses. Items of unusual size have different behavior compared to regular objects. One can pick them up and drop them elsewhere only once. On a subsequent retrieval and drop, the item will return to normal size. They appear the same in one's inventory, but will be the first of which that will be dropped.*

** This rule does NOT apply to Fallout New Vegas or TTW. When picking up differently sized items, they will be in the inventory in the same order you picked them up. For example, if the player picks up 3 stimpaks with the first 2 picked up being undersized and the the third being normal, when the player drops one of the 3 from the stack, it will be the normal sized one as that one was the last one obtained. The differently sized items must be picked up LAST in order to be dropped FIRST.**
