Electronic lighters are used to ignite burners, such as large commercial burners, industrial burners, and even household stoves. The gas types can be ignited are propane, natural gas, and city pipeline gas. These lighters are made of stainless steel, and we produce small, medium, and large sizes. They are great for handyman, as a result of no batteries needed, no flints , and no fuses. The minimum lifespans of the lighters are over 30,000 times of use.
