Max Burton is the brand – they are out of Korea (kovea?) and the mix is: 20% Propane, at least 60% Isobutane, and the remainder <20% n-Butane. They have been working great on my snow peak stoves and are nearly half the price of most other canisters in that size around here. They seem to stock them pretty regularly in out on the Kitsap Peninsula and around Tacoma.
