Our Brooklyn made oil diffusers come in our popular candle scents. Made from non-toxic and phthalate-free oils, our diffusers will last up to 3 months. They come with 6 diffuser reeds. Directions: Remove the cap and place the reeds into the oil, then flip the reeds over and expose the oiled ends. If used in a smaller space, such as a bathroom, use fewer reeds.
