Small box, designed to hold a gift card or cash, that can be locked with a padlock. I gave these out with a set of lock picks that came with a transparent practice padlock as christmas gifts. Locked the gift card and keys inside and printed a 2d barcode on the outside with a link on how to lockpick https://www.youtube.com/watch?v=mO3mMYwKkKs The area where the lock hooks is not super strong and you can rip the lock off with enough force if you become impatient.
