These cases have many nice features and keep the contents dry. They are nowhere near as hard as they should be. I bought 2 small, 2 extra large and some power tools in these hard cases. I transport my tools in a pickup truck so it's important to keep them dry. The bad part of this review is that the plastic on these cases is brittle and breaks easily. Pieces broke off from each box. I don't scatter them. This happens when I load them in and out of the bed of my truck. I'm afraid to pack more tools into a very large suitcase. I don't think it will work.
