Material and design: This lighter is built from metal. The body features a retro relief design with a multi facet surface, enhanced by electroplating, polishing and grinding to create a shiny, textured and durable finish. Windproof performance: The windproof hole design enables incoming air to support combustion, helping to produce a stable flame even in adverse weather conditions. Ignition method: Uses a classic grinding wheel for ignition. A simple slide of the grinding wheel generates a flame, providing an easy and convenient lighting experience. Refilling instructions: To refill with kerosene, pull out the lighter liner first, turn the lighter upside down, lift the felt bottom pad, pour kerosene into the liner, restore the felt bottom pad, and put the liner back into the lighter. Practical use scenarios: Ideal for outdoor camping or hiking where wind exposure is common; suitable for outdoor cooking, barbecues, and other events requiring a reliable flame; useful in emergency kits, home, or travel kits for quick access to a flame.
