there is a plastic box opener in the outer box, which is called mouse gadget. Attached to the corner of the outer box, it is used to poke the transparent glue outside the box to avoid the inconvenience and embarrassment of receiving keys for express delivery and ballpoint pens. These details are done in the design of the outer packing box. Squirrels are very easy to identify and remember. Squirrels can create a lively, lovely and friendly brand image in brand promotion, which can make people have a good association and impression on the brand when they smile at each other. In terms of advantages, I personally think that the three squirrels have grasped the user experience, grasped the psychology of consumers, and met the needs of consumers at the same time, with novel design. There are a series of accessories, gifts, tasting clothes and so on. And there are wet wipes, garbage bags, receipt cards and thank-you notes. Let consumers feel that there is both love and warmth. The title of the thank-you note is "master", which is fun and childlike.
