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.

You can get butane and arc lighter inserts for zippo shells. I’ve had the arc lighter for going on 3 years, I’ve only had to charge it 5 times, it’s gone through the wash twice now and it’s still working great.

Bought my best friend the butane one the same time. She’s a heavy smoker, not only is it her conversion starter but apparently it’s been cheaper than buying bics.
