I also liked the idea of having quality PSK items sealed in a solid, water proof, w/o perishable items like meds or food, could last decades. Just have to make sure to glue a p-38 can opener on it as a back to the pop lid. Made be a plastic cover if you do open it? Oh by the by bought a AMK SOL-3 kit it blew chunks, what a waste of $50. The original Ritter PSK kit is tons better. Would anyone like see to a review of that SOL3?
