The online shopping cart has internally designed structural knife lines and reconstruction methods. After using the packaging box, consumers can use a utility knife to cut the graphics along the structural knife lines according to the illustration and assemble them into toys to achieve the purpose of reuse. The design of the packing box is suitable for adults and children to transform together. It can not only deepen the feelings of adults and children, but also improve the children's abilities of operation and thinking, and help children develop intelligence. However, it should be noted that the modification of the packing box must not allow the child to operate independently, because the child accidentally cuts his finger with a utility knife, and even if the adult and the child transform together, they need to pay attention to protecting the child's hands.
