I bought a box of iced Caribou Coffee in these aluminum containers at my local Sams Club. The neat thing about these containers is that they have metal threading (which I have determined to be fairly difficult to find), and they are rather lightweight compared to other aluminum containers similar in design. You could probably use these in the wintertime for re-melting water in case it freezes on you. I just figured I'd put it out there... It holds 12oz and weighs 0.8oz (24g)
