I remember getting a letter from my childhood penpal on black paper and thought it was the most amazing thing ever. I really do miss them and the black paper notebooks that they were made to write on so they'd show up better.
I definitely had this exact Polly Pocket set as a kid! Back when Polly actually fit in your pocket. And no one had to tell us, "Don't choke on Polly Pocket," because we weren't stupid enough to eat her.
