The flat wick is made of high-quality fiberglass or cotton material; see also wick3, which is made entirely of cotton (without fiberglass), ensuring even combustion—for hours of use without needing to readjust. Universally applicable and precisely cut – compatible with most brands and models of kerosene stoves. Thanks to its well-thought-out design, it can be installed quickly and without tools – ideal for quick wick changes even on the go or in an emergency. Made from durable, robust materials.
