Toggle latches are available to renew your case latches.
For folks that get beyond those irritating stock plastic cases there are different organizing and storage solutions. FWIW, for sockets, I use the metal clip on organizers in the different sizes (1/4", 3/8", and 1/2") to keep rows of sockets stored. The rows of sockets are put into a larger toolbox that has all of the other automotive hand tools. In my shop, I have two wheeled bottom/top box combinations, a total of 29 drawers of tools with little space to spare in the drawers. These boxes made my living for a good part of my life.
