Lunchbox (Fallout 76)

Lunchboxes are consumables

Characteristics
When used, lunchboxes provide a 'Very Well Rested' bonus, a +25% XP bonus, along with a random "party favor" social effect in a small radius, with effects lasting for 60 minutes and 15 seconds. The 'Very Well Rested' bonus can stack up to four times at any given time, increasing the overall bonus of the individual effect, up to a maximum +100% XP bonus. Receiving additional buffs will refresh the duration.

The potential temporary perks are as follows:

Locations

 * Can be purchased from Mortimer or Samuel for after completion of Secrets Revealed.
 * May be earned as rank rewards in seasons.

Behind the scenes
According to Jeff Gardiner, the confetti mess effect was created by Mark Teare. Teare had originally created a similar effect for a Fallout 4 internal game jam, in an attempt to have a no-blood option in the game, so that his kids could see his work.

Bugs
An effect of an individual lunchbox can be lost if using certain magazines such as Live & Love 3 and 8. The effect can be lost if a specific random buff is activated, which will deactivate the magazine. Or, if a magazine is activated after a lunchbox, then that effect and the +25% XP bonus may be lost. The conflicting effects are "Plastic Animals" and "So Much Cake."
