Hi, welcome!
That's basically how I started collecting, lol. I remembered the one pony I had as a child, bought one again, and the next thing I know.... lol! Polly Pockets are soooo cute! I had a lot as a kid but lost them in a fire, unfortunately. I'd love to see your collection sometime though! How do you display yours? And does Labyrinth mean the movie with David Bowie? I wasn't aware there were vintage toys for that! That sounds super neat!!
Hope you enjoy it here in the arena, friend!
