The "blind box" toys, first popularised in Japan, have fixated China in recent years, driving a booming second-hand market and decorating the desks of white-collar workers across the country. "Blind box" toys give buyers a sense of mystery, showing a range of possible figures inside, and occasionally giving out a rare and unadvertised figure when opened.
