Those PDY boxes are hobby tough, no worries there. Bought my orange one about 2 yrs ago at a Jobber show for $25, should have bought two just because I have 35+ yrs of hobby stuff. The design hasn't changed nor the materials. Nice solid lock once you close the lid and fold the handle,,pulls the trays up and holds them tight. No between tray spillage if it gets tipped over so long as nothing blocks the spaces between. The only thing for improvement that I could see is for the upper tray to have round bottoms to the individual compartments, so you can drag small screws or tools out a bit easier. That's just a personal preference thing, other than that they are great. Get two if you are a multiple modeler.
