Suitable for outdoor camping, using magnesium alloy fire-fighting materials ( special treatment, good stability ), with the friction of the side of the metal sheet, it can instantly emit high-temperature and high-brightness sparks, 5000 – 12000 times of ignition, high reliability, almost adapt to any climate and Used under ambient conditions to add convenience to camping, barbecue, and heating. Other products are often affected by harsh environments. Such as air pressure, atmospheric oxygen content, water, wind, and so on.

Material: magnesium alloy Step 1: Hold the bottom edge of the magnesium rod against the ground and scrape some of the magnesium chips on the rod with a blade. Note that the blade should be perpendicular to the magnesium rod when scraping the magnesium. Then the scraped magnesium chips are integrated into a small pile near the flammable materials ( paper leaves, twigs, bark, etc. ) Step 2: Place one side of the magnesium rod against the ground at an angle of about 45 degrees. About 2.5 centimeters from the magnesium scrape that has been scraped off. Use a blade to scrape quickly to effectively scrape the mars. The blade should be scratched. This will cause mars and burn the magnesium to provide you with a white flame. How to use: Use a scraper to scrape off a portion of the combustion-supporting material in a small pile of hay, leaves or paper, and quickly draw a magnesium strip to produce Mars ignition. When the flame is generated, a thin wooden stick is added to form a flame. Features: waterproof, economical, easy to fire
