the search for a metal survival kit container is a subject that just about drives me nuts..


Here are a few more survival kit containers. These are more of the step up in size from the pocket EDC altoids and BCB mini mess tin PSK containers.

The BCB Stainless Crusader Steel Mess Tin (tough and a nice size but slighty heavy)

Or the Laken Hard Anodised Aluminium Mess Tin, which replaced a Sigg Alu Box Midi.
