Polly Pocket is a line of miniature dolls and playsets created by Bluebird Toys in 1989. The toys are known for their small size and compact design, allowing children to easily carry them around. Each set typically includes a doll and a themed environment, such as a house, car, or adventure scene, which can be opened and closed like a compact. In 1998, Mattel acquired the brand and continued to produce various Polly Pocket collections. Over the years, the toys have evolved in design and style, incorporating more detailed features and accessories. Polly Pocket remains popular among children for imaginative play and storytelling.
