Cage : 5VKB6
Original government use unknown. We have a limited overrun of waterproof Delrin® safes. We are not quite sure what Uncle Sam is putting in his lightweight capsules, but we are using ours to keep small important items close and secure. Brand new, never used, overrun from government contract.
Possible uses include:
Tested it under water for 20 minutes and is truly waterproof. It will hold 18 large strike anywhere matches and a striker strip. You can strike the matches on the knurling on the outside of the safe but it takes finesse. The safe is good and strong, whatever goes in it will be safe till you need it.
