**PLEASE NOTE THAT DUE TO FEDERAL REGULATIONS, WE ARE NOT PERMITTED TO SHIP OUR LIGHTERS FILLED WITH BUTANE.** Our high-quality, cute Kuromi lighters are made with PVC and produce an open flame. The lighter is ignited by pulling down Kuromi's ear, which has the perfect resistance profile to allow the lighter to be ignited with minimal force, while still ensuring the lighter does not ignite accidentally in a pocket, purse, or bag. The lighter also has a keychain included as well! Please note that due to federal regulations, we are not permitted to ship our lighters filled with butane. Our lighters can easily be filled with butane and a standard filling nozzle - please refer to the instructions in the photo gallery of this listing on how to do so. The filling port also contains a valve that can be spun to adjust the size of the flame.
