Using the UCO Stormproof Sweetfire Firestarters is super easy. First, take one of the 8 individual 'Points' and break it off from the connected set. Then, use the striker on the box or one of the extra strikers inside to light the strikeable tip of the 'Point'. Once lit, it will burn for about 7 minutes, giving you plenty of time to start your fire. When it comes to safety, remember that this item is considered dangerous goods, so it can only be shipped to NZ addresses. Also, keep it away from children and use it in a well - ventilated area. As for maintenance, store the box in a dry place to ensure the strikeable tips and the overall product stay in good condition. Enjoy your outdoor adventures with these reliable firestarters!
