_y doll is a kind of plush toy filled with bean-shaped PVC (polyvinyl chloride). It was first invented and produced by Harold Ty Warner, an American, and Ty Inc, which he founded, and set off a very amazing whirlwind of collection, trading and speculation in Europe and America at the end of 1996. Although Warner claims to have the name right of "Doudou Baby" and the technical patent of this stuffed bean doll, it still cannot prevent many imitation or even imitation doll products from appearing in the market.
The success of dolls has made Ty one of the largest toy companies in America. With the same concept of sandbags, the company has further developed other product lines with different appearance materials or modeling styles, including baby dolls. However, the prototype is still the core commodity that stands firm.
