Supply Box

A Supply Box is a container item originally introduced for providing PvP only consumables. It's a reward for winning PvP instances, but also can be purchased at PvP vendors.

Nowadays any such box will contain a random general purpose supply consumable.

Trivia

 * In late 2012 all PvP only consumables were changed to general purpose supply items which can be used in PvE instances as well. Thus the decriptive term "PvP Supply Box" which had originally be coned for these items was not longer valid.
 * As of May, 2013, supply boxes still are available from PvP vendors, but since Influence as a currency was phased out with game update 25 at least their availability at vendors remains to be seen.
