KNOX incense cones are that good. Selected raw materials of the highest quality are freshly ground and immediately processed. Dried in a gentle process, the natural raw materials and ingredients are preserved, giving the incense cone its distinctive aroma and traditional scent from old, time-honored recipes. The incense cones have an almost unlimited shelf life without losing their pleasant fragrance. Suitable for incense burners starting at a size of 15 cm, and of course also for our popular metal incense houses!.
