This smartphone package can express the individuality of a user. The cartoon characters on the package represent the unique characteristics of the product. The exterior design is the product's strongest feature as the emotional expressions of the characters are on view. The action of separating the box by detaching the sleeve is intended to resemble the action of attaching/detaching the front cover of the product. The visually repetitive design of the package was inspired by nesting dolls that are placed inside one another.
