The Car Fragrance Sticks are solid aroma-therapy sticks manufactured from plant extracts. The aromas are not only less volatile than those of diffusers, but also healthier. For use in the car, the fragrance sticks are inserted into a compact, aluminium cylinder that is attached at the ventilation outlet. The aroma concentration can be adjusted via a rotary switch. If the fragrance stick is switched off, it rests in an almost completely closed container, so that the aroma can hardly escape.
