Vault-Tec lunchbox

The Vault-Tec lunchbox is a miscellaneous item in Fallout 4. When interacted with it spawns a random item and becomes collectable.

Characteristics
A Vault-Tec branded lunchbox with depictions of Vault-Tec propaganda and various versions of Vault Boy. The inside of the lunchbox has faint drawings of children's faces on the front and rear of the box. These drawings are difficult to see under normal circumstances, as the lunchbox is usually thrown around upon opening, and players often pick the item up immediately without inspecting it. Occasionally, a lunchbox will have a sticker decal, or the name of a child on the front. It is currently unknown whether the appearance of decals and names is randomized.

Each lunchbox contains a randomly selected item, ranging anywhere from junk items like a fork or plastic knife, to the rarer items such as ice cold Nuka Cola Quantum or a collectible model.
