Barbie The Diamond Castle Singing Princess Liana Doll is a 12-inch fashion doll manufactured by Mattel in 2008. The doll features a battery-operated singing function and comes in its original packaging. The doll's hair color is blonde and hair type varies. It has a gender-neutral appearance and a Caucasian ethnicity. The doll is part of the Barbie product line and the Barbie franchise. The set includes the doll and is suitable for all occasions. The doll's theme is fantasy, and it is an original, licensed reproduction.

The packaging has damage. The outer packaging has been open but the doll has not been taken off the inner card. The sound doesn’t not work. Hopefully it’s just a dead battery but can not guarantee that. See photos for details.
