Welly tin.
They're those cute tins filled with themed bandaids you can get at Walmart. Normally they're brightly colored and targeted to small kids. Not only are they pretty good fabric bandaids but the tin is really reliable as a homemade med pack for camping. Small, light, brightly colored, and stupidly durable. Had mine in my bag for about 5 years now and it hadn't even dented.
