The Sparky handheld Piezo stove lighter from optimums ignites with the simple press of a button. Holes at the tip allow a bit of gas into the tube, and the Piezo mechanism creates a small electric Spark for safe and reliable ignition. This Piezo lighter uses no fuel, so you'll never have the unpleasant surprise of a lighter that has run dry. The Sparky works with canister and liquid fuel stoves, comes with a lanyard and fits comfortably in your hand during use.
