If you carry a Zippo, I'm pretty sure you have experienced a time when you ran out of fuel when you needed it most. This Zippo fuel canister clips on to your gear or key ring and not only stores extra fuel but also has a space for two extra flints.
This lighter uses zippo lighter fuel as an accelerate and works in pretty much the same way. It also utilizes an old Bic lighter and some copper and brass tubing. // Great for if your a Metro 2033 fan!
