Muji's Ultrasonic Aroma Diffuser. * Model number: HAD-001-JPW * Purchased new in-store in 2021 * Measuring cup not included (I lost it.) * Box and instruction manual included. Used about 30 times, so it shows some signs of use, but it's clean and in relatively good condition. I mainly used Muji's aroma oils "Relaxing Blend" and "Sleep Blend," so it might have a slight scent of those. I have confirmed that it works before listing. Please refrain from purchasing if you are overly concerned about minor details.
