We began in 1997, when J.K. Rowling sent a boy with round glasses and a lightning bolt scar into the world. We are the letter that arrives by owl, the moving staircases, the platform you can only reach if you already believe. We are Harry and Hermione and Ron, the Hogwarts houses, the spells learned by heart. Over twenty years we became the best-selling book series in history, a film franchise watched by generations, a world so complete that people visit it in theme parks and carry it in their pockets. Pop Mart brought us into blind boxes — each figure a small piece of a universe that never quite ends.
