This is the Jet Washer WF309. I purchased it about a month ago and used it twice, but it didn't suit me, so I'm selling it. The nozzles for orthodontic care, plaque removal, periodontal pockets, and tongue cleaning are all new and unopened. It's IPX7 waterproof, so it can be used in the bathroom. I will lightly wipe it down with alcohol before shipping. - Model Name: WF309 - Included: USB cable, instruction manual, 4 types of nozzles, tank - Color: White - Function: Jet washer for oral care Thank you for looking.
