No clue- though they do say the reservoir is visible. Maybe someone who does product reviews will take this up (hint, hint). <img src="images/graemlins/grin.gif" alt="" />
That's probably not a huge factor for me personally, as I don't smoke. Whatever the capacity is, it's going to be a lot more than storing a few matches. I'm thinking EDC here, not as a primary firestarter for either kits or wilderness trips.
And, per an earlier thread, it's got a corkscrew! Some of us find that more or less essential for EDC...
