Extra wicks are good to have, and work with Lamp Oil or Kerosene. Each lantern comes with a wick installed. If you plan to use your oil lamps regularly, then an extra set per lantern is recommended. One set of 1/2" wicks is 5 x 8" pieces, approximately 40" in total.
1/2" flat wick is a standard size for many different lanterns. If you change fuel types, its recommended you change to a new wick.
