Timburn Kindl-Steel is a durable 14 guage stainless steel cylinder that surrounds and protects the high-temperature ceramic block. The system acts as a wick for Timburn fire starter oils. The Kindl-Steel starter system will last for years. It delivers a high, hot flame for 9 to 11 minutes using only 1.25 ounces of Timburn liquid and will start nearly any fire.
