I purchased this in 2021 and used it for about 2-3 months, but I didn't make it a habit, so I'm selling it. The condition is relatively good, but as you can see in photos 3-6, there are some dirt and scratches in the crevices. Regarding the nozzles, the tongue cleaning nozzle and the point cleaning nozzle are unused. I recommend that you prepare a new ultrasonic water flosser nozzle, but if you don't mind, I will include the used one (disinfected with baby bottle disinfectant). I have cleaned it thoroughly, charged it, and confirmed that it works (5 levels). Please consider this item only if you understand that it is a used item based on the images and description. — Brand: Panasonic Power Source: Battery-powered Features: Air Technology Product Features: Gum Health Number of Units: 1 Color: White Supports 1-hour quick charging Tongue cleaning nozzle (1 included): EW0985 *1 Water flow that generates ultrasonic waves due to the shock waves when bubbles burst.
