This is our new locker design called "PolyStore," named for its extensive space. This new locker design will allow students to store their backpacks, books, binders, personal items, lunch bags, and more. A single unit of this locker consists of the main octagonal compartment and a small cube compartment for storing lunch bags and personal items. The doors of this locker are opened in sections, in order to avoid injury. The locker also includes two shelves for books on the locker floor and one shelf for small items and books. In addition, the locker includes two hangers and a picture frame for pictures and posters. A mirror is located in the small cubic compartment. Thus, this locker solves the following problems: space for backpack and books, decoration and personalization, injury-free doors, and space for storing lunch without compressing it.
