Only lunch box to withstand 'The School Boy Frizbee Test' (IMO)!
Plastic is heavier duty than the Cube/Bento Lunch Boxes.
Compartments seal completely, no leakage.
Lid is convex, lots of space to cram snacks in.
Also, it fits in the Sistema To Go Cooler Bag ½ Price @ $6 too.
No need to focus on that feature…
