Vintage Polly Pocket

Please see photos for condition. There is a yellowing tint to some of the white parts of the exterior of the castle. It runs on 4 “AA” batteries but even after changing batteries the unit is not lighting or playing music. The unit is not complete and missing some of the pieces. It does come with 10 figures (some of these appear to go to another Polly Pocket set-Cinderella is in this lot) to the playset. It does not have the key to “unlock” the castle but a small flathead screwdriver will unlock it.
