Unscrew the silver collar, carefully remove the plastic stopper and then replace the silver collar. Insert between 4 and 8 reeds (depending on the strength of fragrance desired) into the essential oil. The reeds will absorb the fragrance to perfectly scent your room. The rattan reeds can be left unattended or you can remove the reeds and replace the stopper for occasional use. Inverting the reeds or increasing the number of reeds will strengthen the fragrance. Do not light the reeds. Flammable. Keep away from flame or high heat.
