I ran in to this industrial looking parts organizer today at homdepot. The body is hard plastic and the handle  looks  aluminum. Feels super durable. At first i saw the small trays inside and figured i wouldnt be able to use it but then i opened it up to find larger ones on the bottom. The top is very clear so you can see exactly whats inside. The trays are removable. The top looks solid and the clasps are metal eliminating the possibility of the thing flying open while your carrying it. See the lame blurry iphone pics below :).
