I'm looking for a box that can fit in my flight bag to hold a survival kit. Ideal size would be about 9x11x1.5 inches. The 9x11 is pretty much maximum, but the 1.5 inches can go either way. About the size of a ream of paper. Plastic or aluminum, water tight would be preferable but I can tape it up if it isn't.

Clipboard boxes that you can find at any office supply store are just a little too big, although now that I think about it I should check it again.

Another thing everybody is looking for is a box about the size of an Altoids tin, or maybe a little bigger. A clamp that holds it shut would be ideal, sort of like the Sigg Midi or Maxi box, but smaller.
