It all started going downhill when they started making houses instead of compacts. The houses were small, yes, but oddly shaped, and putting them in your pocket would a) be difficult and b) hurt a lot.
I remember my first Polly Pocket. It was a circular purple compact that fit nicely in my pocket, maybe a bit snug, but it was POCKET SIZED. I loved it because I could take it everywhere.
These new toys are NOT Polly Pocket. They are Polly Shelf.
