Caps stash (Fallout 4)

A caps stash is a one-time use tin full of bottle caps.

Characteristics
A blue tin full of bottlecaps. It is not an item that can be placed in the inventory, but rather like a bobby pin box in that it adds a random amount of bottlecaps. In Fallout 4, this number of bottlecaps is limited from 14-23. In Fallout 76, there is a chance that this number can go over 100 in rare caps stashes that play an animation when they are found. Companions in Fallout 4 can pick up the caps stash as an item, which the player character can take out of their inventory.
