The flare consists of a paper tube filled with a pyrotechnic composition and attached to a wooden handle. The top of each flare contains a button of ignition material. A friction striker is provided with each signal.
The flare is ignited by scraping the top of the inside cap against the forward end of the pyrotechnic mixture. Hold the flare in an inclined position while burning, to prevent drippings from burning the hand.
Nothing else to see.
