If you know essential oils, you know Young Living. I bought this car vent diffuser a few years ago and never opened it. I just found it while cleaning. I also have a small bottle of Peppermint Vitality oil that I never opened. no idea why I bought it since I don't like the smell of mint. 🤣 The diffuser comes with 6 discs you can swap out for different scents. You don't even have to use Young Living oil with it.
