The 'Really Useful Boxes' are now my favorite storage boxes. They are super-sturdy, the lids are rock solid and not wimpy flexible like many others I've tried and the side lid-latches work 100 times better than the normal snap lids.
I'm buying a few dozen of different sizes before they go out of production like all good things.
The timer is fantastic as well.
I got mine from Target Online (not offered at stores) for $15 and everyone at my FLGS wants one now for Space Hulk, Civ, etc.
I'm ordering a second one to use for it's intended purpose in the kitchen
