A special orange promotional MagicBand was given out today ahead of a special Star Wars: Galaxy’s Edge press event for invited media and guests. The MagicBand is not available for purchase and is only given as a gift. From what I understand, the press event is today with the official dedication being held tomorrow August 28th, 2019. Below are some pictures of what it looks like.
