This design is aimed at preventing the express list from revealing personal information after abandoning. When you want to abandon the express list, you can pull a densely-arranged plastic strip hidden underneath the express list. While pulling the strip, the express list is being destroyed, as well as the personal information written on it. It is characterized by easily operating and without the aid of other tools. It is especially applied to those who do not want to reveal personal information but give up because of trouble. Meanwhile the production process is simple and the cost is low.
