Yeti,
The survival instructions and reflective tape in lid of tin are those that came with the BCB "Military Survival Kit" that I bought on Ebay. I bought the breast milk bags at the local market. They are on the small side, about 350 ml, but a lot more serviceable than the two rubbers that came with the original BCB kit.
