Roy Roger's Lunchbox

Origin
Time capsules are common school projects. Children place letters or items for their future selves. The capsule is then buried and retrieved at a later date, usually decades later.

Effects
When food is placed inside of the lunchbox or thermos it will be perfectly preserved at the same temperature it was upon entering. When the food it stored is eaten the consumer will feel nostalgia from their childhood.

Collection
Hugo Miller collected the lunchbox from a time capsule project done at a school in middle America. The warehouse tries to keep itself abreast of all time capsules to guarantee safety from an artifact. When Hugo returned with the lunchbox another agent ingested the perfectly preserved sandwich inside it. That particular agent was the "Pete" of the warehouse.
