I couldn't help but notice that the tin RYP has the HEST/F packaged in seemed really familiar to me! I had bought several about 6 months ago to make some survival kits out of since it's just about the perfect size and thickness for one. It's slightly longer and wider than the Pelican and Otter Boxes in it's size range, but the nice thing is it's WAY thinner. It also is waterproofed by coming with a thick rubber gasket on the lid, seals shut with the clamps on the side, and is made of aluminum. It's VERY sturdy so you don't have to worry about the thing crushing or falling apart on you either. Here are some pics of one survival kit that I had thrown together in one of them. I also have a plastic handcuff key, 25' of 175lb. test kevlar cord, and a solid ceramic razor blade inside that are not pictured. There's still room inside for several more items to be added. *Maybe someone could post the photo of the HEST/F packaged in the tin on here so people can see what I'm talking about. I'd REALLY appreciate it!!! This is a 1 Quart water bag and Katadyn chlorine dioxide tablets for water purification.
