I had to remove this showerhead after only one day because the water pressure at my home was too weak to utilize its full functionality. I purchased it from Amazon for around 3000 yen. I'm offering it to someone who understands the situation. It's a浄水 (purifying) showerhead with two filters and water pressure adjustment. - Product Name: 浄水 Showerhead - Filter Type: 304 Stainless Steel Filter - Included: 2 replacement filters, 3 adapters - Design: Simple and elegant design - Features: Water pressure adjustment Thank you for looking.
