Purchased in December 2025 and used only once for testing, I'm selling it to declutter. It uses a jet spray to remove plaque that can't be removed by brushing alone. The removable tip was used once, but for those who don't mind, or if you'd like, I will include it after sterilizing it with boiling water and alcohol. It's almost new, but since it's an oral care item, I'd like to sell it to someone who doesn't mind or wants to try it out. Feel free to ask any questions! Immediate purchase is also welcome if you have no questions. #OralCare #OralIrrigation #ElectricToothbrush #Doltz #BeautyAppliance
