High quality 7/8″ Cotton Wick. Each lantern comes with a wick installed, and its good to have some spare when you need replacements. If you plan to use your oil lamps regularly, then a couple sets per lantern is recommended.
One set of 7/8″ wicks is 5 x 8″ pieces; approximately 40″ total. A very common wick size for many different lamps using Queen Anne #2 Burners.
Fits our model numbers: 500 series glass lamps, 250, 9919, 9920.
