 * Purchasing them from the store
 * Completing quests from the overseer's office
 * Weekly report every seven days after the vault was created if the happiness is 100%
 * Drop from random wasteland encounters (on dead bodies)
 * After collecting the rewards from the daily report for seven days in a row. The seventh reward is always a lunchbox.
