Straight from our "Apothecary of Fragrant Goods" we bring you our acclaimed diffusers as refills. Filled into a squeezable, sleek plastic bottle, you can now refresh your 1803 diffuser or create your very own using any clean glass bottle or jar. Simply fill the jar with our diffuser refill oil and fill with a bundle of rattan reeds. Diffuser refills come prepared and ready-to-use in squeezable plastic bottles sealed with a threaded cap. Diffuser refill reeds are sold individually.
