These 1/8 inch round olive oil lamp wicks are small, cylindrical wicks typically made from tightly-braided cotton, ensuring effective fuel absorption and steady burning. With a diameter of 1/8 inch, these wicks are suitable for smaller lamps or specific types of burners that require a narrower wick. They are designed specifically for use with olive oil, a traditional and eco-friendly lamp fuel. These wicks draw olive oil from the lamp's reservoir to the burner, where it is vaporized and ignited to produce light. Commonly used in decorative or historical lamps, religious rituals, and as a sustainable lighting option in homes or outdoor settings, these wicks are essential for the efficient and reliable operation of olive oil lamps, providing a clean and steady source of light. Long-lasting, tightly-braided cotton. 12-pack. 1/8"OD x 10"L. Fits Merry Corliss Olive Oil Lamps: Chamber Lamp, Table Lamp, Camp Lamp. USA made.
