+1 for the Lock&Lock plastic boxes. I bought mine from a kitchenware shop near my parents, if I had to find them locally I am not sure where I would go. I find that the genuine Lock&Lock are significantly better than the generic supermarket versions. The clips on the supermarket ones do not always clip down, or stay that way over time. I use these boxes for food, including dressed salad, but also for pocket size expedition fishing tackle, first aid kits, camera and electronics when I am canoeing and general small parts and treasures that I want to stay together and be protected from damp.
