Smoke Odor Exterminator products contain natural enzymes that help to exterminate odor from the surrounding atmosphere. The enzymes absorb the odor from their surroundings into the product, then the enzymes break down the odor's compound structure, and evaporate the by-product in the form of a clean, natural gas. During the evaporation process, the gas picks up the scent of the product and releases this fragrance into your office, home or car; exterminating the odor and creating a pleasant fragrance for your enjoyment. Unlike other "odor eliminating products', ours do not just mask odors but destroy them. Our candles are a blend of paraffin and soy wax, and a zinc wick, which will ensure a cleaner and longer burn time. Tobacco Outlet Products is proud to say ALL of our products are made in the U.S.A.
