My Favorite Dollar Store Sells These bright Xmas red Circular Metal Enamel Coated Containers with Tupperware Style lids in 3 sizes. 4Inch Bottom With 5inch Lid Top and 2 inch deep, 5inch bottom with 6 inch top and 2.5 inches deep, 6inch bottom 7inch top 2.5 inch deep.

Well The smallest is easily comparable to my current PSK size at 4x5x2 Inch rectangular. With being a Circular container it is a tad bit more bulky and being metal it is a bit heavier.

My Current PSK offers no way to purify water via Boiling or tablets. Switching to the metal container will add a greater capability over adding a length of foil to my current one. Needless To say switching over to metal from plastic adds the benefit of container strength and removes the shatter risk of rigid plastic.

So which do you think I should go with?
