COMPANION Iso-Butane Gas 220g 4 Pack

These cartridges feature resealable valves which allow the can to be shifted between different appliances, even when there is gas left in the cartridge! Pair this with a whopping shelf-life of 8 years and you can be sure that these butane cartridges will never go to waste.

Rim Vent Release (RVR) technology releases gas and balances pressure within the can to prevent explosions when the pressure rises over the normal level.

Can last up to 1hr and 45 minutes per canister in a single burner stove at high output (dependent on variables).
