An iPhone Case You Can Edit: In the event of a zombie apocalypse or a ship wreck, this iPhone case may save you from starvation. At least for day or two. Made from rice and salt, the $81 Survival Senbei Rice Cracker iPhone 5 Case is part phone case, part emergency snack. Japan Trend Shop says, "If you want a case that will provide 100% protection, don't get this one. It's literally made of rice so probably will break if dropped. However, then you can always eat it! A tongue-in-cheek design that shows the Japanese obsession with both tech and cuisine, we just love this!"
