Lunchbox (Fallout 3)

The lunchbox is a miscellaneous item in Fallout 3, Fallout: New Vegas and Fallout 4.

Characteristics
This was a promotional item created by Vault-Tec before the Great War and used in the company's advertisements. With the right schematics, it can be used to make bottlecap mines.

In Fallout 3, a lunchbox can be used to make a Bottlecap mine at workbenches.

In Fallout: New Vegas, a lunchbox can be used to make a caravan lunch at campfires or a bottlecap mine at workbenches.

In Fallout 4, attempting to take a lunchbox will first make it pop open in a shower of confetti and spawn a random small item. This is a reference to Fallout Shelter.
