That's true. I hadn't considered the interior dimensions of a plastic case. I picked up an altoids size tin at a gun show. It's two pieces with a gasket. My thought was to press it closed, sealed with a bead of silicone, then electrical tape. Possibly an over seal in a vacuum bag. I doubt she'll baby the kit like some of our customers do, so the more rugged it is, the better. I see major's surplus has a kit in a plastic box, "designed by a survialist for survivalists." Mhmm a survivalist who wastes space with a paracord bracelet instend of compressing it. Great tip Izzy. Thanks.
