Specific Doll Dream Valley Maurren- wings and arms?

Was hoping to see photos of the way Dream Valley Maurren's arms and wings work. From the photos and videos shared by Dream Valley, it looks like there are magnets on the sides of the "peg" that goes into the armpit joint- is that accurate? I'd love to see the arms unstrung and check out what the "peg" looks like. Is there a hook to string the arm's elastic through?
