I'm selling these at a bargain price because I have accumulated too many and no longer use them. There are 10 adult-sized brush heads. I have so many that I'm also listing other items. I can adjust the number of brush heads and offer children's sizes, so please feel free to consult with me. I'd prefer orders of 10 or more. I'm also including the main unit as a bonus (used). A charging cord is also included. Please let me know if you don't need the main unit. In that case, since the unit is a bonus, there will be no discount. #ElectricToothbrush #Gareido #ReplacementBrushHeads #ElectricToothbrushMainUnit
