The official Disneyland Magic Key Holder Instagram account posted a photo of the sunglasses moments ago. From February 1 through February 28, while supplies last, Magic Key holders can pick up a pair of these sunglasses at the corridor near the entrance of Cars Land in Disney California Adventure Park, across from Blue Sky Cellar. There will be a limit of one pair of sunglasses per Magic Key holder.
Along with the sunglasses, Disneyland also announced new drinks and merchandise that will be available to purchase for Magic Key holders. For more details, read our post here.
