The Betty Spaghetty® dolls in this set all differ from the dolls released in the US and UK.
Each doll stands approximately 18cms tall and can be pulled apart.
All parts are interchangeable between dolls:

Lucy with removable hat and carrying a purse,
Betty with removable hat and backpack,
Mandy with a mirror,
Hiroko with her pet panda which clings to her arm.

The dolls' hair can be pulled to make it longer and the heads turned to make the hair shorter.
