Wrapped Gift

Somebody put something in here, and you find out what only by opening it. The game calls it lazily wrapped, and that fits: a player makes this gift with wrapping paper, so it holds exactly what that player chose.

That makes it the best prank of a December wipe. Your teammate leaves one next to the Christmas tree in the main room, you unwrap it hoping for ammo, and out falls a rock. It works the other way too: a real kit for a friend feels better when it has to be unwrapped first.

Do not mix it up with the event's own presents. A small present comes from the Christmas event itself; this one only ever holds what a person put in. You cannot craft or research it, so a Wrapped Gift exists only once somebody wraps one.
