Abstract: A bag includes a back wall having a hook accommodating the hanging of the bag when opened, a plurality of compartments on a front surface of the back wall, the plurality of compartments having a front portion being of a mesh material accommodating a view of the objects and a circulation of air within the compartments. The compartments can have shelves projecting from the back wall to accommodate the objects. The wall can be folded or rolled to close the back wall into the bag for carrying by the handles through hands or on a back of a user. A locking bar on a zipper enclosing the bag can be used to secure the bag to a locker.
