Brand New, Unopened 【Ultra-Fine Water Flow for Gentle Skin Feel】 Powerful showers emerge from 0.3mm ultra-fine holes drilled into a stainless steel shower plate. The number of holes has been increased to approximately twice that of conventional models, achieving a unique and denser shower experience. It reaches the scalp effectively, quickly rinsing away shampoo. 【Water Saving of Approximately 50%】 You can stop and start the water flow with the stop button on the handle when you want to pause. The specially designed shower plate provides a comfortable shower experience with less water. 【Increased Water Pressure】 Boosts the water pressure of weak showers, which can be a problem in homes with low water pressure. 【Compatible with Most Manufacturers】 Directly installable with manufacturers [SANEI, TOTO, LIXIL (INAX) except for balance-type water heaters, KAKUDAI, TBC, YUKO, MIZUTANI, and some MYM products], and installable with the included adapter for manufacturers [KVK, MYM (thick hose)]. Manufacturers installable with a separately sold adapter (Part Number: PT250-9) [Some MIZUTANI products (if direct installation is not possible)]. ⚠ Cannot be used with balance-type water heaters, mixing faucets without a backflow prevention mechanism (check valve), or two-valve mixing faucets without a temporary water stop function (only shower ⇔ pipe switching). 【Maintenance】 If you feel that the shower flow is disrupted or the water flow is poor, you can easily clean the shower plate by removing it.
