6" Adventure Dolls
These are 6" Adventure Dolls, released in North America by Irwin (I'm not 100% sure about this). As you can see I have Moon, Mercury, Uranus, Neptune, and Pluto - click on the name to see the individual doll.
I've had these since I was young, and I used to play with them, so their hair is no longer perfect and I don't have the boxes. They all come with their gold transformation wands, except for Neptune who has her mirror and Uranus who has her sword. Moon and Mercury have rotating moon locket bases.
