This is the MYTREX HIHO FINE BUBBLE showerhead. Using micro-nano bubble (fine bubble) technology, it enhances cleaning effectiveness with bubbles smaller than pores and hair. Water-saving effects can be expected. It has the effect of improving skin's moisturizing and heat retention abilities. I have used it for about a year. Since it is used, please refrain from purchasing if you are sensitive to used items. Price reduction is not possible.
