WoW Anniversary Items No Longer in Inventory

All the items in the Anniversary Gift are temporary and will only last as long as the Anniversary Event is active. You can check if the event is still active by looking at your in-game calendar. Once the event ends, the items will be removed from your inventory.

The Celebration Package is consumed on use to add an experience and reputation buff that lasts during the whole event. If you lost your buff or Celebration Package, you can purchase another from Historian Ma'di located in Caverns of Time.
