I don't think there really is mysteries to see with the key. I've watched many reviews & not one person has seen anything that can't be seen with the naked eye 😂 But the keys are pretty, so I'm keeping them, when I get a doll.
Bought this doll yesterday! I’m a big Draculaura fan but I would’ve liked to get Abbey more… I got her because Draculauras in my area always sell out fast and never restock. I still think she’s adorable though!
