Wow, a ready-made coffin! That thing better be made out of titanium kryptonite if a building, a redwood tree or a mountain or something larger doesn’t crush it flat. Better hope there’s no fire either or your just cooking yourself in an oven. And I don’t see any Depends in there for when you gotta poop or pee if you’re stuck for days on end. I see they included gas masks though to protect yourself from the stench. Hope the sides kick out somehow if something lands on top of it and heeps the lid from being able to open. And no DVD player and porn stash to keep your mind off your situation while you wait for someone to [hopefully] discover you. Unless it has an alarm bell you can trigger or cell phone/internet service so you can at least let someone know where they can find your body.
