The design redefines the piggy bank and creates a banknote pocket for the image of the candy package, giving the paper bag a certain function and expectation. When it is full and tears open, getting a complete coin is like getting the joy of candy, bringing a new psychological feeling to the money-taking behavior. Disposable materials make "carrying" and "taking" very contradictory behaviors. Once the seal is opened, the piggy bank loses its "rescue" effect, leaving only a sweet feeling like candy.
