Kerosene Brass Lighter 100% solid brass, brushed finish 2 1/8 x 2" Refueling Your lighter runs on standard lighter fluid. To refill, simply remove the metal insert from the case. At the bottom, you’ll see a cotton filling—this is where the fluid goes. Slowly saturate the cotton until it feels slightly damp, then reinsert the insert into the case. Wick Maintenance The wick is designed to last, but over time it will burn down. When the flame gets weak or low, use tweezers to gently pull up the wick from the top and trim off the blackened end. This refreshes the flame and keeps it burning clean. Replacing the Flint The flint (the small stone that creates the spark) will wear down with regular use. When you notice the spark is weak or gone, it’s time to replace it. Unscrew the flint spring at the bottom of the insert to remove the old flint and drop in a new one. Replacements are available online or at most smoke shops—standard sizes will fit.
