These boxes are perfect! cheapest price by far was here on optics planet. - MTM P-100 Fliptop Box .380/9mm Luger

These look really good and they are built even better. Really seem sturdy and rigid even when fully loaded, the lid is firm when shut almost a slight struggle to open which I think is great because sometimes plastic snaps can be less that solid. The hinge works perfectly and allows the lid to have full rotation. The lid can flip around and lay flat to act as a Trey to hold all of the rounds you are dropping into the slots. I bought 12 of these and I will be buying more!
