Well, the Barbie is well known doll from Mattel, but the house for Barbie is another story. First house for Barbie appeared in 1960, so they had some time to improve it a little bit.
So here is Barbie 3-Story Dream Townhouse. Hm. 3 stores is nice, it's about 1,5 meter in height making half a meter per floor. That is quite enough. For average girl size to play with such game.
Materials. Yes it's plastic, what you were waiting for $28. It's hard to destroy accidentally, though if there is enough child in the family, a boy, the the life time of Barbie 3-Story Dream Townhouse will be quite short
From outside it looks like non-finished engineered 3d construction without walls. Why not, if it got wall there will be no chance to view what inside. I wonder does Mattel supplies the walls separately, you know, just in case.
The toy, or it is better to say, game for girls will be suitable for the young ladies age from 6 to 12. I think it is good present jut to fill in empty space in the girl's room, don't forget to properly spray it with antistatic liquid so the dust will not get nasty inside. I cooperation with a set of Barbie dolls this townhouse can bring much fun for the quite long period of time, and stay as a collection or part of furniture in the room.
