i have 3
"meth-ods" sorry!
1 just take it in the container it was sold in!
2 i have 2 tiny bottles designed to hold sterile water to wash contact lenses, together they'd hold half a pint ish, good thing is they have a squirty top so no more spilt bottles you forgot to close! also you can direct the fuel if using it to light a fire!
3 i have 2 bottles origionally hand wash soap containers (with a push button on top) like the sort you probably have in your bathroom.
the re-fills come with a sealed lid. after use i cleaned them both really well, they hold i guess 1 liter which is more than enough for a weekend.
2 will cover a week easily!
good thing is they're see though so you don't have to guess how much is left, they are squashy,
not brittle), and i'm not and no one else going to accidently drink from them as they are nothing like sigg bottles!
they've seen -7 degrees, and +30 and they are safe!
and free i've been useing them for 4 years with no problems!!
another i have (the same type contains unleadeed petrol for my MSR stove, again no problems! and you can see which is petrol and meths!
