CROSS-REFERENCE TO RELATED APPLICATION(S) 
       [0001]    This application claims priority to U.S. Provisional Patent Application Ser. No. 62/112,891 filed on Feb. 6, 2015 and entitled “Food and Crayon Snap-Locking Containers and Adjustable Shelving”, the content of which is hereby incorporated by reference in its entirety. 
     
    
     BACKGROUND 
       [0002]    Multiple food containers require using both hands and/or stacking containers to move them. The snap lock container allows for multiple containers to be carried with one hand. 
         [0003]    Crayon boxes require two hands to reach for and pick out a crayon without the box tipping over. The snap lock crayon box allows for one hand to pick out a crayon and easily find the favorite crayon without searching. Carrying food containers in a bag requires a haphazard storage in a soft material bag which may lead to spillage or loss of storage space for books. The adjustable shelving system for bags allows for purposeful storage of food containers of any shape.
