The waterproof odorless fire starter sticks are practical for everyday use both indoors and outdoors. They are cylindrical with a rectangular cross-section adapted for safe ignition when lit. The flame produces minimal amounts of smoke, making it safe to use in closed spaces. Each stick burns approximately 6 to 8 minutes and burns at a temperature of 680˚F. Each box weighs approximately 1.4 oz with 100 minutes of burning time. They are resistant to moisture, and easy to ignite.
