I bought this for storage in my classroom.  I have two, and knowing how wild the students can be, I taped both of them together to enable them to be sturdy enough to handle elementary students.  Each student will have a container case with their personal supplies.  This will be tested well with each student going to get their assigned drawer.   The individual containers fit nicely in the desk.  They do not seem to snap close easily.  As I am setting them up for the next school year, I suspect that items will spill out if not handled with both hands clasping the top and bottom of the case. 
 Both storage chests arrived promptly and packing was done well.
