I'm looking for small aluminum containers that are water proof. The high impact plastic ones are to large and bulky for my purposes. Ideal size would be about 4" h x 6" w x 1" deep, with some sort of rubber/silcon seal and latching mechanism. Anybody got a source? REI, EMS use to carry something like this prior to all the bulky high impact plastic ones. Thanks for the help. <br>Icebite.
