Released in 2019 as part of a Castle Series, the Walt Disney World Cinderella Castle backpack is one of the more rare Loungefly backpacks on the market today. When you can find one, it can easily sell for over $800. Other than the castle, the bag don’t have a lot of features. It does have gold zippers though, a front pocket, and the interior liner has various signs from the lands in Walt Disney World.
