Directly from our Apothecary of Fragrant Goods®, we bring you our acclaimed diffusers in a refill option. Filled into a squeezable, sleek plastic bottle, now you can refresh your 1803 room diffuser or make your very own using any vintage glass bottle or jar. Fill the jar with our diffuser refill oil and set in a bundle of rattan reeds. The bold River Birch fragrance will scent your homestead in the spirit of Simpler Times Renewed®. Diffuser refill reeds can be purchased individually.
